Anyone in network security knows that it is a complicated and involved process. The clear goal is to prevent security breaches. How do you go about that though? There are so many schools of thought, methods, and configurations. Here are just a few examples: Cyber range trainingCyber resilienceDefense in depthEncryptionEndpoint securityFirewallsInli...

Security is nowadays an important part of network management. Secure networks are vital for running an uninterrupted business, preventing data loss and maintaining the overall image of the business. Security challenges are increasing because networking is getting more complex, more dynamic and virtual. The existing approach of network visibility li...

​The importance of having a quality network test access port (TAP) when conducting Digital Forensics and Incident Response (DFIR) has been covered in a white paper by Profitap, titled "Special Tool for Special Forces: Tapping into real-time threats in the cyberspace". In addition to the points presented in the white paper, I would like to provide a...

In a recent webinar, Best Practices for Security Resilience, Jon Oltsik (an analyst from ESG Research Group) and I discussed the topic of network security resilience. The basic concept is that it is not a question of "IF" your company network will be breached, but "WHEN". The real question for you to answer is, "How painful do you want that breach ...

Welcome to the third annual Security Report issued by Ixia, a Keysight business. Each year, the Ixia Application and Threat Intelligence (ATI) Research Centre summarizes the most interesting and prominent internet security trends. We analyze ATI data to help organizations understand where they can improve. We also analyze the data to predict the bi...

​The IT role is extremely hard today. Whether you are part of the DevOps or SecOps team makes no difference - threats and problems are a daily, if not hourly, occurrence. What you need is good quality data as fast as you can get it to counter security threats, troubleshoot network outages, and remediate performance problems. Unfortunately, IT ...

One of the most common forms of network threats today is distributed denial of service (DDoS). An attack involves flooding networks and servers with false internet traffic, thereby blocking access to genuine devices. Sometimes used to target specific businesses, cyber-attacks can bring down entire telecoms networks, as was the case in the attack on...

​Cyber defenses encrypt data to keep it safe while hackers encrypt malware to sneak threats onto your network. A new report from Enterprise Management Associates (EMA) says enterprises see the new Transport Layer Security (TLS) 1.3 encryption standards as offering greater privacy and security—over 70 percent of respondents have or will start enabli...

​In the webinar above,the concept of network security resilience and how to implement it is explained. However, successful implementation relies upon making the fundamental mind shift to the strategy. One cannot expect to see the benefits if they don't embrace change. ​However, change is easier said than done. It seems like many security engineers,...

Cybersecurity is a hot topic today. Hackers are always looking to undermine our network connections and we are always trying to protect against them.  I'm no cybersecurity expert, but I am often asked, "Can Resilient PNT be used to improve cybersecurity?" Resoundingly, "YES"  Here are a few simple examples:  1. Passwords - Most secur...

While security experts may disagree on exactly how to secure a network, one thing they all agree on is that you cannot defend against what you cannot see. In other words, network visibility IS network security. Visibility needs to be the starting the point. After that, you can implement whatever appliances, processes, and configurations you need to...

Every day we hear of security breaches, which damages the company brand and reputation.  At the present time the advantage has been with the attacker and the CISO is now expected to provide meaningful and actionable security intelligence to board members. So how can CISOs train tomorrow's security executives when today's well-known securi...

A delicate balancing act is taking place on networks globally. It is the balance between applying strong protective measures to keep data safe and unintentionally concealing new IT security vulnerabilities. And it all centers on SSL (Secure Socket Layer) encryption. Just as SSL encryption protects certain details of a transaction, it can also conce...

Unlike traditional, reactive approaches to detection, hunting is proactive. With hunting, security professionals don't wait to take action until they've received a security alert or, even worse, suffer a data breach. Instead, hunting entails looking for opponents who are already in your environment. Hunting leads to discovering undesirable activity...

It has finally happened: thanks to advances in encryption, legacy security and monitoring tools are now useless when it comes to SSL. Read this white paper from Ixia, to learn how this negatively impacts visibility into network applications, such as e-mail, e-commerce, online banking, and data storage. Or even worse, how advanced malware ...
