For several years, most news articles about a computer, network, or Internet-based compromise have mentioned the phrase "zero day exploit" or "zero day attack," but rarely do these articles define what this is. A zero day exploit is any attack that was previously unknown to the target or security experts in general. Many believe that the term refers to attacks that were just released into the wild or developed by hackers in the current calendar day. This is generally not the case. The "zero day" component of the term refers to the lack of prior knowledge about the attack, highlighting the idea that the victim has zero day's notice of an attack. The main feature of a zero day attack is that since it is an unknown attack, there are no specific defenses or filters for it. Thus, a wide number of targets are vulnerable to the exploit.

Does your company have a risk management program? In this hour-long webinar, cybersecurity expert and Global Knowledge instructor David Willson will explain why you should. In light of recent breaches at Target, Nieman Marcus, Michaels, Yahoo, and a growing list of others, we're learning that FBI Director Mueller was right when he said getting breached is not a matter of if, but when. While having a risk management program may not prevent a breach, it can certainly lower the risk of one, ensure compliance, and reduce or even eliminate your liability if a breach does occur, enabling you to recover quickly and to protect your reputation. Beyond explaining the importance of a risk management program, David will tell you how to implement one, including conducting a basic risk assessment, policies you'll need, and training your workforce.

While the last few years have brought about many great advances in IT and network technology security and risk management have a critical point. There is a host of new concerns the IT security manager must be concerned with, including social networking, mobile, cloud, and information sharing. This has unleashed a new wave of change and potential risk. Risk management is required to deal with these emerging technologies and should provide the rationale for all information security activities within the organization. You can think of risk management as the process of ensuring that the impact of threats and exploited vulnerabilities is within acceptable limits at an acceptable cost. Risk management requires the use of countermeasures. Countermeasures can include any process that serves to reduce threats or vulnerabilities.

The Internet is not a safe place. We see that more than ever with the security breaches of businesses and individuals in the news on a daily basis. As Internet citizens, we need to take our protection into our own hands, as obviously most online services are not doing their best to protect us.

Many employees are not as well-versed in their company’s security policy as they should be. This may result in workers performing tasks that might seem innocent or benign on the surface, but which actually put the organization at risk of a security breach. Understanding what you are doing (as an employee) or what your users are doing (as a boss or manager), can help you work toward a viable resolution to these situations. In most cases, user behavior changes as well as implementation of new technological solutions can curb exposure to risk and increase security policy compliance.

These technology job roles are proven to be essential during a crisis as enterprises scramble to change strategies and meet goals. The skills demonstrated by IT professionals in these 10 positions can make the difference between business success and failure, especially during a recession.

Rather than looking back over the past year, organizations and individuals need to start assessing cybersecurity threats that lie ahead in the New Year. While there is always the chance for a new threat or risk to be unearthed this year, often the risks of the New Year are predicable from the trends of attacks from the previous year. However, other factors need to be considered as well, including new technologies, new software and applications, mobility, etc. Here are my predictions of the areas to watch for new security threats. When it comes to cybersecurity, we have a lot to look out for, take precautions against and be paranoid about.

National Cybersecurity Awareness Month has grown into a global effort, with both individuals and organizations taking part — and for good reason.

Attackers use a method called scanning before they attack a network. Often attackers use automated tools such as network/host scanners and war dialers to locate systems and attempt to discover vulnerabilities.

Once an attacker gains access to the target system, the attacker can choose to use both the system and its resources and further use the system as a launch pad to scan and exploit other systems, or he can keep a low profile and continue exploiting the system.

An attacker needs to destroy evidence of his presence and activities for several reasons like being able to maintain access and evade detection (and the resulting punishment). Erasing evidence of a compromise is a requirement for any attacker who wants to remain obscure and evade trace back. This usually starts with erasing the contaminated logins and any possible error messages that may have been generated from the attack process.

Use cases are an effective and widely used technique for eliciting software requirements. In this hour-long webinar, software development and process improvement expert Karl E. Wiegers will introduce you to a practical and straightforward use cases approach to requirements elicitation.
