Hackers are everywhere, and they have a sophisticated array of tools for cracking your passwords. The primary purpose of this white paper is to help you understand that easy-to-remember passwords are no longer considered a secure form of authentication. You should consider any static password that you can remember as vulnerable. Even static passwords that are random are still vulnerable to some extent - It just takes much longer for a password cracking attack to be successful, and the likelihood of that success is inversely proportional to the length of the password. Here are some tips to help you create effective passwords, and how to keep your passwords safe.
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.
Risk is something we deal with on a daily basis. Living in New Jersey and having the occasional storm, I’ve recently performed my own risk assessment determining the value of certain assets and activities and made a decision on what I was willing to spend to reduce risk to what I perceived as an acceptable level. My management of risk was a rather simple case. Sure, in my revised business continuity plan for my home, I’ll make sure that I have more D cell batteries, have my garage door adjusted so it opens manually again, more food I can heat on a stove and that doesn’t rely on refrigeration, and finally I’ll consider a whole house gas generator that uses natural gas, which has always been available to power critical systems like the sump pump in my basement. What if, however, I was a really large business? One with lots of components and interdependencies that require a tight integration in order to succeed? How and where can a large volume of information necessary to management, business continuity, and disaster recovery be correlated and communicated to those individuals who, because of their roles and responsibilities, need to make the critical decisions regarding the management of risk?
Learning how to program and develop for the Hadoop platform can lead to lucrative new career opportunities in Big Data. But like the problems it solves, the Hadoop framework can be quite complex and challenging. Join Global Knowledge instructor and Technology Consultant Rich Morrow as he leads you through some of the hurdles and pitfalls students encounter on the Hadoop learning path. Building a strong foundation, leveraging online resources, and focusing on the basics with professional training can help neophytes across the Hadoop finish line.
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.
Course director Jim Thomas explains how our custom labs, which utilize external hosts, ISR routers, and DMZ, provide a real-world environment for students.
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.
Global Knowledge instructor Doug Notini discusses the benefits of our FIREWALL 2.0 - Deploying Cisco ASA Firewall Solutions course.
Dell SonicWALL's CSSA (Certified SonicWALL Security Administrator) exam is an open book, online certification exam that certifies a student’s understanding of the SonicOS Unified Threat Management (UTM) operating system. The exam tests a student’s network security knowledge, and their ability to use the GUI menu structure for configuration of standard network security scenarios.
Constant change in the technology landscape has been mirrored by the steady evolution of information security. The current information system environment is increasingly complex, comprising storage, servers, LANs/WANs, workstations, Unified Communications, Intranet, and Internet connections.
