Cyber-Digital Task Force

The Department of Justice’s internal “Cyber-Digital Task Force,” created by Attorney General Jeff Sessions in February, will release its first-ever public report later this month at the Aspen Institute’s annual Security Forum, a department spokesperson told CyberScoop.

The report is expected to detail a series of security recommendations that the government should consider to protect future U.S. elections from a myriad of different threats, including foreign hacking attempts.

A statement by the DOJ previously explained that the Task Force will “prioritize its study of efforts to interfere with our elections; efforts to interfere with our critical infrastructure; the use of the Internet to spread violent ideologies and to recruit followers; the mass theft of corporate, governmental, and private information; the use of technology to avoid or frustrate law enforcement; and the mass exploitation of computers and other digital devices to attack American citizens and businesses.”

When Sessions launched the group earlier this year, he requested that an initial report be completed by June 30. The recommendations were submitted ahead of time, according to DOJ spokesperson Ian Prior. The answers are currently being reviewed ahead of publication.

The DOJ’s disclosure was made hours after the Democratic National Committee (DNC) issued a press release criticizing the department and Trump administration for missing various cybersecurity policy deadlines, including the June 30 submission. The agency contends that it in fact made the deadline, although the publication won’t occur for a few weeks. The Aspen Security Forum begins on July 18.

The creation of the Cybersecurity Task Force on Feb. 20 came less than a week after Special Counsel Robert Mueller indicted a group of Russian internet trolls for interfering in U.S. politics. The Russians allegedly ran an extensive social media campaign that worked to trick American voters in the run-up to the 2016 presidential election, the indictment claims.

Deputy Attorney General Rod Rosenstein is expected to make “an exclusive policy announcement” on July 19 at the Aspen Institute event.

Secure all networks, from the Internet?

In the coming years in 2019-2020, the active mobile users will cross the 5 billion mark globally, and add to this the number of tablet user will also increase. When we analyze these figures it is not difficult to estimate that there are more than 20 million IoT devices in the pipeline ready to hit the base by 2020. It means the above-given figures are all set to be part of the connected world.

All these devices mean lots of valuable data, and where there’s valuable data there are hackers trying to get access to it. Not only do we need to wrestle with new kinds of networks, many of them wireless, but we need to tackle the security of these networks while simultaneously tackling the massive scale of the problem.

Now imagine the kind of valuable data that will be churned out from these devices, and how it will be a gala time for the hackers to break into these devices and get access. No doubt we need to bring such device in our daily life, but the challenge is to get them all secured taking into account the massive breach in the line.

We asked vendors and resellers how they approach security of the WAN in this challenging environment

The internet is the network

The data center is no more the enter of the universe, but it is the Internet that new network that brings all the network closer to each other.

Mobile phone networks are rapidly being repurposed as a general-purpose data network over which voice calls are just one more application. Inside the telcos themselves, the core networking is already running over IP networks, and consumers are very comfortable with messaging applications that talk over IP networks instead of SMS. Devices in the field are adding LTE interfaces as a cheap and easy way to add networking capability to what were once disconnected devices.

“We have to rethink how we approach things,” Kopelke says. “We need to change our thinking from ‘How do I secure and protect the network?’ to ‘How do I secure and protect the data and applications?’”

Gavin Wilson, Asia-Pacific managing director at Cradlepoint “People expect to always be connected. Increasingly the connection is a mix of technologies, rather than a single layer-1 or layer-2 approach.” Instead of a loose collection of isolated technologies, the network is now an abstraction operating at a higher level, and there is no longer a functional difference between “the internet” of decades past and what all these modern mobile devices use to connect”.

The connected world and benefits

This ubiquitous networking is enabling associations to do things that basically weren’t conceivable previously. Without a system to send the information, gadgets in trucks or conveyed by field laborers would need to store information for later use. Presently they can stream a lot of information back to a server farm or straight into the cloud, and they can be inconsistent contact with different parts of the framework.

“The ability to get information out to remote people is a massive benefit, and, if a truck roll over on a delivery, an immediate duress notification can let others know the driver is in trouble,” says Michael Dyson, general manager at Advanced Mobile IT‌

“We also have digital signage that can be remotely updated,” Dyson says. “You can receive diagnostics from remote locations without having to send a technician out to the site and there are buses in New Zealand that can do on-board ticketing and have a GPS for accurate next-stop announcements.”

As it turned out to be consistently more steadily and reasonable, the requirement for the specialist like; satellite telephones, CB radios have dropped abruptly. These more seasoned technologies are turning into a fallback — as opposed to the essential strategy for building up correspondences. The generously higher transfer speed access, combined with the across the board accessibility of the supporting framework, influences the cost/to profit examination straightforward: you’d be distraught not to.

Security

Obviously, simply being associated isn’t sufficient. We likewise need to keep information and applications secure when they’re interfacing with an indistinguishable web from each content kiddie and solidified digital crime with a hunger for other individuals’ data.

“The traditional way to secure the WAN was using firewalls at each branch or backhauling branch traffic to a datacenter and use firewalls there to protect the traffic,” says Stree Naidu, vice president. Asia-Pacific and Japan for Cato Networks. “As long as we think about the firewall as a box that sits somewhere, that box defines the perimeter. But what if the perimeter was defined by a firewall that is everywhere? This is the notion of Firewall as a Service (FWaaS).”

Moving from the physical system of security that is as pervasive as the availability itself is it all about. “Systems that are secured from commencement is the name of the diversion. Rather than being a bit of hindsight or an extra, security in a world with no border implies heating it in from the start.

“It has to be about more than taking an appliance and virutalizing it,” says Zscaler’s Kopelke. “We say that’s just cloud-washing.”

Cato Networks’ Scree agrees. “The challenge most organizations face is how to extend enterprise-grade security to all their branches and mobile users globally,” he says. “Cloud networks with built-in network security can offer a way forward.”

“With users expecting a higher standard of service, these standalone appliances won’t cut it anymore,” says Dell EMC’s Elmarji. “You need to be able to provide full security on all connected devices, fast access to data, and 24/7 connectivity.”

While it’s still relatively early days for software-defined networks, it’s clear where the momentum is. Customers and resellers alike should be investigating how they can move to using software-based networking to create the secure, ubiquitous networks of the future

PGP vulnerability? Exposes PGP Encrypted Email

German researchers have found a major vulnerability in PGP (Pretty Good Privacy), a popular email encryption program, which could reveal past and present encrypted emails.

Sebastian Schinzel, professor of computer science at Münster University investigated the flaw, tweeting that full details of the vulnerability will be available from 15 May. 

He said: "they might reveal the plaintext of encrypted emails, including encrypted emails sent in the past."

We'll publish critical vulnerabilities in PGP/GPG and S/MIME email encryption on 2018-05-15 07:00 UTC. They might reveal the plaintext of encrypted emails, including encrypted emails sent in the 

Anyone using PGP to encrypt their email could have their messages exposed thanks to a severe vulnerability for which there's no proper fix. That's according to researchers in Germany, who said anyone using plug-ins allowing simple use of PGP should stop using them entirely and possibly delete them too.

The warning came from Sebastian Schinzel, lead of the IT security lab at the Münster University of Applied Sciences, who noted attacks exploiting the vulnerability "might reveal the plaintext of encrypted emails, including encrypted emails sent in the past." Though he isn't revealing the full details until Tuesday May 15, the findings have spooked security-conscious folk.

We'll publish critical vulnerabilities in PGP/GPG and S/MIME email encryption on 2018-05-15 07:00 UTC. They might reveal the plaintext of encrypted emails, including encrypted emails sent in the past. #efail 1/4

The Electronic Frontier Foundation (EFF) said it had reviewed the research and could "confirm that these vulnerabilities pose an immediate risk to those using these tools for email communication, including the potential exposure of the contents of past messages."

"Until the flaws described in the paper are more widely understood and fixed, users should arrange for the use of alternative end-to-end secure channels, such as Signal, and temporarily stop sending and especially reading PGP-encrypted email," the EFF wrote in a blog post.

The EFF has also offered guidance on how to remove plug-ins associated with PGP email, which users can find on the blog. Those plug-ins include ones for clients Apple Mail, Thunderbird and Outlook.

It appears the vulnerability (which some have dubbed eFail) resides in such email clients, rather than a fundamental problem with the PGP standard, according to Werner Koch, the man behind GNUPrivacyGuard (GnuPG), the free and open source PGP software suite. In a post, Koch said he believed the EFF's comments on the issue were "overblown" and that he hadn't been contacted about the vulnerability.

This vulnerability might be used to decrypt the contents of encrypted emails sent in the past. Having used PGP since 1993, this sounds baaad. #efail

They figured out mail clients which don't properly check for decryption errors and also follow links in HTML mails. So the vulnerability is in the mail clients and not in the protocols. In fact OpenPGP is immune if used correctly while S/MIME has no deployed mitigation.

PGP was long seen as the standard for encrypted messaging and it remains the most popular method of sending private email. Increasingly, however, mobile apps like Signal, Apple's iMessage and Threema have provided simple methods for end-to-end encrypted communications.

Schinzel hadn't responded to a request for comment at the time of publication. He's done significant work on cryptographic weaknesses in the past; in 2016, he co-created an attack dubbed DROWN (Decrypting RSA with Obsolete and Weakened eNcryption), which could decrypt people's web connections on 33 per cent of all HTTPS websites.

A trick to decrypt

The researchers explained in a website for the eFail vulnerability that it required the attacker to be able to intercept and email and tamper with it to reveal the plaintext of messages. "In a nutshell, eFail abuses active content of HTML emails, for example externally loaded images or styles, to exfiltrate plaintext through requested URLs," they wrote.

"The attacker changes an encrypted email in a particular way and sends this changed encrypted email to the victim. The victim's email client decrypts the email and loads any external content, thus exfiltrating the plaintext to the attacker."

The full technical paper is available here.

An old flaw

A spokesperson for ProtonMail, a webmail service that uses PGP, confirmed its services were not affected. The spokesperson also eFail wasn't exactly new. "It has been known since 2001. The vulnerability exists in implementation errors in various PGP clients and not the protocol itself," the spokesperson added.

"What is newsworthy is that some clients that support PGP were not aware of this for 17 years and did not perform the appropriate mitigation.

"As the world's largest encrypted email service based on PGP, we are disappointed that some organizations and publications have contributed to a narrative that suggests PGP is broken or that people should stop using PGP. This is not a safe recommendation."

Apple gets fixing

An Apple spokesperson said partial fixes to eFail were released in iOS 11.3, which shipped March 29. The remaining fixes for affected Apple products being developed and will be with customers soon, they added.

Microsoft said it had no comment on the matter.

CISO Roles Expanding - Global Risk Management

Traditionally, the mission of the CISO has been to convince the CEO of the capabilities the organisation must put in place to prevent and follow-up on threats and manage crises. At the helm of IT security, CISOs are in their element overseeing the security operations centre (SOC), incident response teams and forensics experts to address threats. But now, many are being forced outside of their comfort zone. With global attacks dominating television news and headlines in Europe, US and the UK, cybersecurity is top of mind for CEOs and their Boards. And this means that the role of the CISO is expanding.

The Evolving Role of the CISO: Handling a Crisis When You Aren’t Under Attack

The Evolving Role of the CISO: Handling a Crisis When You Aren’t Under Attack

According to Aon’s 2017 Global Risk Management Survey, cybercrime is now number five among the top 10 concerns for risk decision-makers globally, above failure to innovate, failure to attract and retain top talent, business interruption, political risk/uncertainties and third-party liability. Each time a high-profile attack happens, the CISO gets a phone call from the CEO asking questions like: Are we at risk? Should we be doing something? It is no longer enough to let the CEO know that the organization has not yet been attacked. CISOs need to expand their leadership role and actively engage in risk management.

I have had the opportunity to speak with many CISOs who validate that their jobs are changing.

“Before, we had to fight to explain to the CEO that it would be interesting to know what was coming in and out of our systems,” said Benoit Moreau, CISO of the French ministry of national education and research. “Now, we are expected to have a fine perception of each element of our ‘information ecosystem’ and the interactions that drive it to succeed to predict, almost in real time, the consequences of any stimulus. Our systems have undergone a dazzling Darwinian evolution, driven by new technologies and uses. They went from monocellular organisms that were individually secured to complex protean organisms close to life.”

Today, when the external threat landscape changes and the CEO inevitably calls, CISOs need to respond differently. They need to have situational understanding, be prepared to make decisions on the spot and communicate how they will ensure risk remains at an acceptable level. Moreau explains, “The CISO must equip himself to have ‘awareness’ of the security infrastructure as a whole – to feel the problems, to detect the symptoms. He must understand weaknesses, threats and health risks. He must strengthen his defenses, have the means to carry out further analysis in case of doubt, to inoculate or provide other treatments, and even to amputate in the event of the spread of deadly agents. It is no longer a question for the CISO to deploy some white blood cells, but to be the healthy mind in a healthy body, a robust organism with an effective immune system.”

As a CISO, what does it take to embrace this important change in your role? To begin with, you need instant access to as much information as possible about an attack or campaign. This includes an adversary’s targets and motivations; their tools, techniques, and procedures (TTPs) including tactics and vulnerabilities that may put the organization at risk; as well as the countermeasures available.

Most organizations already have much of this information, but it is spread across many different departments, in multiple external threat data feeds, in your layers of security products, in your SIEM that store logs and events and in analysts’ brains. What you need is a single source of truth – a centralized repository for all this data that you can continuously augment and enrich so that it is contextualized, relevant and prioritized. With a hub for storing, updating and accessing threat intelligence, your teams can learn and share knowledge to assess whether a threat poses short-term danger and determine the appropriate actions. But barriers remain.

Traditionally, siloed teams work independently and in a vacuum without the ability to collaborate throughout the analysis process and execute a coordinated response as needed. Working on parallel tasks, they can miss key commonalities. All teams must be able to work together in a single shared environment for a greater understanding and focus throughout the situation analysis and response process. Using visualization and documentation they can quickly see threat data, evidence, and actions across all the various departments and individual involved in the investigation.

With visibility into this collaborative environment and the situation analysis as it unfolds, CISOs can coordinate between teams and actions taken. A global picture provides the information you need to reply with greater confidence to your CEO’s questions. You can gauge if you’re adequately prepared to withstand an attack and let your CEO know. Or, if not, you can direct the appropriate action faster and assure your CEO you’re taking the right actions to mitigate risk.

Reacting to massive, global threats is a new phenomenon and a new responsibility added to CISOs’ day-to-day tasks. The moment you become aware of a potential new attack, you must be able to assess risk, anticipate potential impact and start crisis management. When a threat is detected, you must be able to respond quickly and comprehensively while maintaining business continuity. It’s no longer enough to protect the organization from an attack – you must be able to handle a crisis even if you aren’t under attack.

(NIST) Framework Cyber Security Updated

Four years after the initial iteration was released, the National Institute of Standards and Technology (NIST) has released version 1.1 of the Framework for Improving Critical Infrastructure Cybersecurity.

The framework was developed to be a voluntary, risk-based framework to improve cybersecurity for critical infrastructure in the United States. It’s the result of a President Obama-issued executive order calling for the development of a set of standards, guidelines and practices to help organizations charged with providing the nation’s financial, energy, health care and other critical systems better protect their information and physical assets from cyberattack. 

Like the first version, Version 1.1 of the framework was created through public-private collaboration via a series of recommendations, drafts and comment periods. Changes to Version 1.1 includes updates on authentication and identity, self-assessing cybersecurity risk, managing cybersecurity within the supply chain and vulnerability disclosure, among other changes.

For one, the update has renamed the Access Control Category to Identity Management and Access Control, to better account for authentication, authorization and identity-proofing.

It also has added a new section: Section 4.0 Self-Assessing Cybersecurity Risk with the Framework explains how the framework can be used by organizations to understand and assess their cybersecurity risk, including the use of measurements.

On the supply-chain front, an expanded Section 3.3 helps users better understand risk management in this arena, while a new section (3.4) focuses on buying decisions and the use of the framework in understanding risk associated with commercial off-the-shelf products and services. Additional risk-management criteria were added to the Implementation Tiers for the framework; and a supply-chain risk-management category has been added to the Framework Core.

Other updates include a better explanation of the relationship between Implementation Tiers and Profiles; added clarity around the term “compliance,” given the variety of ways in which the framework can be used by an organization; and the addition of a subcategory related to the vulnerability disclosure lifecycle.

“This update refines, clarifies and enhances Version 1.0,” said Matt Barrett, program manager for the Cybersecurity Framework. “It is still flexible to meet an individual organization’s business or mission needs, and applies to a wide range of technology environments such as information technology, industrial control systems and the Internet of Things (IoT).”

Its goal is to be flexible enough to be adopted voluntarily by large and small companies and organizations across all industry sectors, as well as by federal, state and local governments.

              Nist > 1.1

The release of the Cybersecurity Framework Version 1.1 is a significant advance that truly reflects the success of the public-private model for addressing cybersecurity challenges

“The release of the Cybersecurity Framework Version 1.1 is a significant advance that truly reflects the success of the public-private model for addressing cybersecurity challenges,” said Walter Copan, NIST director. “From the very beginning, the Cybersecurity Framework has been a collaborative effort involving stakeholders from government, industry and academia.”

So far, adoption of the framework has been fairly widespread: PwC’s 2018 Global State of Information Security Survey (GSISS) for instance found that respondents from healthcare payer and provider organizations, as well as oil and gas companies, said the NIST Cybersecurity Framework is the most commonly adopted set information security standards in their respective industries. The report also found that financial institution clients were widely embracing benchmarking of their cyber risk management programs against the NIST Cybersecurity Framework.

“Cybersecurity is critical for national and economic security,” said Secretary of Commerce Wilbur Ross. “The voluntary NIST Cybersecurity Framework should be every company’s first line of defense. Adopting version 1.1 is a must do for all CEOs.”

Efforts to expand its influence are continuing: In May 2017, President Trump issued the Executive Order on Strengthening the Cybersecurity of Federal Networks and Critical Infrastructure, which directs all federal agencies to use the Cybersecurity Framework. Also, corporations, organizations and countries around the world, including Italy, Israel and Uruguay, have adopted the framework, or their own adaptation of it, NIST noted.

Meanwhile, to help ease the process of adoption, the Information Security Forum (ISF) has mapped the framework and its annual Standard of Good Practice for IT security professionals. Last year, IT governance organization ISACA launched an audit programaligning the NIST framework with COBIT 5, designed to provide management with an assessment of the effectiveness of an organization’s plans to detect and identify cyber-threats, and protect against them.

“We’re looking forward to reaching more industries, supporting federal agencies, and especially helping more small businesses across the U.S. benefit from the framework,” said Barrett.

Later this year, NIST plans to release an updated companion document, the Roadmap for Improving Critical Infrastructure Cybersecurity, which describes key areas of development, alignment and collaboration.

“Engagement and collaboration will continue to be essential to the framework’s success,” said Barrett. “The Cybersecurity Framework will need to evolve as threats, technologies and industries evolve. With this update, we’ve demonstrated that we have a good process in place for bringing stakeholders together to ensure the framework remains a great tool for managing cybersecurity risk.”

Cyber Security Is The Backbone Any Online Businesses – Here Are Some Quick Tips To Keep Yourself Informed About The Latest Threats Surrounding Your Business.

                                    Cyber Security Developments

                                    Cyber Security Developments

Within a standard nine to five working day, it’s said that there are almost two million data records lost or stolen. Cybercrime has become something of an epidemic in recent years – and it’s no exaggeration to say that everyone is at risk.

Hackers operate in an increasingly complex way and are happy to target small businesses and individuals, who are most likely to be vulnerable to attack. The nature of the threat changes as technology advances and so the only way to stay safe is to stay up to date.

But that’s easier said than done, right? How do you keep up to date with the latest cybersecurity developments?

Follow The News

When it comes to cyber security, ignorance is not bliss – it’s a recipe for disaster. It’s imperative that you identify and follow a news feed that you can trust. By doing so, you can keep on top of any fresh threats that have emerged, learn lessons from other cyber attacks and pick up the latest tips and advice from influencers and experts in this field.

News from this sector really shouldn’t be seen as the preserve of IT specialists – the scale and nature of the threat suggest that this should be of interest to everyone. There’s a burgeoning band of podcasts available on the subject for people who prefer to digest content in this way too.

Bring Up The ‘Security Question’

If you think that installing an anti-virus program is enough, then you’re mistaken. Don’t just presume that you’re safe because you have this because this is merely the first line of defense to root out attacks. By adopting a safety first mindset you can ensure that the way you handle your data is less risky.

Whether it’s securing your Wi-Fi network at home, managing and updating your passwords on a regular basis or the way you collect, collate and analyze data throughthe point of sale software at work, continually ask yourself ‘is this safe?’ Just as ignorance isn’t bliss, complacency could prove your undoing. Place ‘security’ high on the list of credentials to consider when buying new software or hardware, don’t just go for the cheapest option.

Training

Even the experts are constantly having to refresh their understanding of the threat posed by cyber attacks. It pays to search out training opportunities, especially if you’re a business. You are, after all, only as safe as the people operating your software and systems and you don’t want to put the security of your business in the hands of someone who is unsure about what they are doing. Individuals and businesses alike can find free learning materials on Cybrary to help plug any knowledge gaps they have.

It’s Good To Talk

Cyber attacks are incredibly common – but people don’t often enough talk about their experiences. Perhaps you’re afraid or embarrassed to have been caught out? There’s no need to be. In fact, talking with friends and colleagues could really help you to stay safe. Pass on tips about new apps, good software, neat tips and tricks and any new cyber attack tactics you have come across and you can help to do your own bit to combat the criminals.

By keeping up to speed with security news, refreshing your training, sharing tips and tricks and adopting a safety first attitude you’ll give yourself the best possible chance of staying on top of cyber security developments and, best of all, safe.

Security Consulting

Many people who sell security products call themselves security consultants and they are part of the security field, but there are also security consultants who don't sell products. These individuals are paid on an hourly or project basis to help clients, usually, corporations, protect their personnel and property. Property security embraces both real estate and tangible equipment as well as other assets like client lists and proprietary technology. Employee and customer theft, as well as piracy, are possible focuses for a security consulting practice. Technical security consultants are knowledgeable about products, such as electronic security systems, including their development and how to apply them. The work may involve system design as well as drafting plans and documents.

Computer Security


While virtually all security consultants employ computer technology in their work, the computer security niche specifically involves protecting computer systems and networks themselves against unauthorized use and abuse. A computer security consultant often specializes in particular operating systems such as UNIX, LINUX or Windows.

Site Consulting


Whether it's new construction or remodeling, virtually every building and office-be it a high-tech industrial complex, retail franchise, distribution center, self-storage facility, housing development, hotel, resort, casino, parking lot or law firm-is interested in some aspect of site security. Security site consultants evaluate the physical design of such buildings and spaces, determine what security problems a sites poses and recommend countermeasures, such as guards, electronic security with cameras and electric lights, or a combination of methods and policies.

System Design


Security system designers develop specifications and provide architectural or engineering support in the design phase of a security consulting project. System designers may also develop new electronic security tools to be used at a particular location.

Forensic Consulting


Forensic security consultants serve as expert witnesses in trials in which security breaches are at issue, such as with fires, thefts, break-ins, and so on. Forensic consultants may specialize in any of the above fields.

As a security practitioner, you can also develop niches for your work based on the type of clients you work with, such as museums or historical sites, shipyards and airports. Unlike professional investigators, security consultants don't have to be licensed by state agencies. However, there are professional associations you can join and certification programs you can complete, which may help foster a sense of trust with your clients. One of the larger associations, which provides certification.

Specializing is key to marketing a security specialty business because it will help you more easily identify and market to clients who need such services, such as architects and contractors or members of a particular industry, such as software developers or law firms. You'll be soliciting work and attracting clients by making presentations and speeches or networking in organizations where you can showcase your expertise. In addition to your knowledge of security, you must be prepared to develop your speaking skills in order to attract new business.

What Is Network Security?

What Is Network Security? - CyberSecOp

Network security is an organization’s strategy and provisions for ensuring the security of its assets and all network traffic. Network security is manifested in an implementation of security hardware and software. For the purposes of this discussion, the following approach is adopted in an effort to view network security in its entirety.

What Is Network Security?

What Is Network Security?

Policy
The IT Security Policy is the principle document for network security. Its goal is to outline rules for ensuring the security of organizational assets. Employees today often utilize several tools and applications to conduct business productively. Policy-driven from the organization’s culture supports these routines and focuses on safely enabling these tools for employees. Enforcement and auditing procedures for any regulatory compliance to which an organization is subject must be mapped out in the policies, and controls as well.

Types of network security

Access control

Not every user should have access to your network. To keep out potential attackers, you need to recognize each user and each device. Then you can enforce your security policies. You can block noncompliant endpoint devices or give them only limited access. This process is network access control (NAC).

Antivirus and antimalware software

"Malware," short for "malicious software," includes viruses, worms, Trojans, ransomware, and spyware. Sometimes malware will infect a network but lie dormant for days or even weeks. The best antimalware programs not only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage.

Application security

Any software you use to run your business needs to be protected, whether your IT staff builds it or whether you buy it. Unfortunately, any application may contain holes, or vulnerabilities, that attackers can use to infiltrate your network. Application security encompasses the hardware, software, and processes you use to close those holes.

Behavioral analytics

To detect abnormal network behavior, you must know what normal behavior looks like. Behavioral analytics tools automatically discern activities that deviate from the norm. Your security team can then better identify indicators of compromise that pose a potential problem and quickly remediate threats.

Data loss prevention

Organizations must make sure that their staff does not send sensitive information outside the network. Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.

Email security

Email gateways are the number one threat vector for a security breach. Attackers use personal information and social engineering tactics to build sophisticated phishing campaigns to deceive recipients and send them to sites serving up malware. An email security application blocks incoming attacks and controls outbound messages to prevent the loss of sensitive data.

Firewalls

Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet. They use a set of defined rules to allow or block traffic. A firewall can be hardware, software, or both. Cisco offers unified threat management(UTM) devices and threat-focused next-generation firewalls.

Intrusion prevention systems

An intrusion prevention system (IPS) scans network traffic to actively block attacks. Next-Generation IPS (NGIPS) appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection.

Mobile device security

Cybercriminals are increasingly targeting mobile devices and apps. Within the next 3 years, 90 percent of IT organizations may support corporate applications on personal mobile devices. Of course, you need to control which devices can access your network. You will also need to configure their connections to keep network traffic private.

Network Segmentation

Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier. Ideally, the classifications are based on endpoint identity, not mere IP addresses. You can assign access rights based on role, location, and more so that the right level of access is given to the right people and suspicious devices are contained and remediated.

Security information and event management

SIEM products pull together the information that your security staff needs to identify and respond to threats. These products come in various forms, including physical and virtual appliances and server software.

VPN

A virtual private network encrypts the connection from an endpoint to a network, often over the Internet. Typically, a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network.

Web security

A web security solution will control your staff’s web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud. "Web security" also refers to the steps you take to protect your own website.

Wireless security

Wireless networks are not as secure as wired ones. Without stringent security measures, installing a wireless LAN can be like putting Ethernet ports everywhere, including the parking lot. To prevent an exploit from taking hold, you need products specifically designed to protect a wireless network.
