Deciphering the Encryption Paradox
As security professionals, we all understand the importance of protecting data and the need for proper encryption. It’s no surprise, then, that more and more traffic crossing our networks is encrypted. This is a good thing from both a security and privacy perspective, but what if the encryption is being used to hide malicious activity on enterprise networks?
Strengthening Cybersecurity's Weakest Links With Deep Network Insights
Like a chain forged of steel, cybersecurity is only as strong as its weakest link. But how can we gain visibility into where these weaknesses exist and how they are being exploited? How can we determine where gaps occur that impact our ability to protect against, detect and respond to the latest threats? Studies have shown the vast majority of cyberattacks take place using our networks — which isn’t surprising in our hyperconnected world.
Digging SOC Analysts Out From Under Tax Fraud False Positives
If you’re on the East Coast, particularly in New England, you’ve likely gotten used to looking out your window at several feet of snow. As soon as we get ourselves shoveled out from one storm, another nor’easter is underway. I can’t help but think this must be what it feels like to work in a security operations center (SOC) during tax (fraud) season.
Online Safety Tips for NCSAM: Lessons From Week One
October is National Cyber Security Awareness Month (NCSAM), which is an annual campaign to raise awareness about cybersecurity. IBM Security joined forces with the EveryApp team to share one tip a day to make people’s online lives safer. Here are their lessons from the first seven days of the month. Getting prompted for Java updates or iTunes? Cybercriminals love it when you don’t install updates when prompted, and they take full advantage of it.
Rinse, Wash, Repeat: Defining, Planning and Continuously Improving Your SIEM Strategy
Designing your security information and event management (SIEM) strategy can be very challenging, particularly in complex environments that depend on many systems and stakeholders. For security leaders, it may seem as though this work is never complete. Indeed, maintaining an effective SIEM program requires a cyclical approach of reviewing business objectives, planning detection and response processes, and constantly tweaking the system to account for gaps and future growth.
Take a Dive: Deep Network Insights for Deeper Analytics
Security analytics are only as good as the data that feeds them. I’m not saying that advanced analytics such as machine learning and artificial intelligence (AI) aren’t amazingly powerful and increasing important for cybersecurity — they are. But unlocking the full potential of advanced analytics requires deep network insights: a combination of the right data, sufficient visibility into the details and context that we care about from a security perspective.
Now Trending: Your 2018 Network Security Snapshot
Security spending is on the rise even as IT allotments fall, creating a conundrum for IT professionals who must deliver top-tier protection in a technology market where cybercriminal innovation and consumer expectations are accelerating. With 2018 just around the corner, it’s worth knowing what’s on the horizon for network security and where IT focus has the most impact. Below is a snapshot of next year’s top network trends.
The Past, Present and Future of DNS Security
The Domain Name System (DNS) is the backbone of the modern internet. Over the years, it has evolved to make networked computing accessible to everyday users. However, it has also introduced new DNS security threats, such as distributed denial-of-service (DDoS) attacks, schemes designed to redirect users to malicious websites and more. Despite these risks, the current configuration of the DNS is deeply embedded into the fabric the internet as we know it.
The Power of Network Insights: Nowhere for Threats to Hide
Picture this: You’re all set to go and have a big day ahead of you, but you can’t find the car keys. Frustrating, right? So is trying to find phishing attacks, lateral movement, embedded malware and advanced threats buried deep within normal traffic as they traverse your network. It’s hard to find what you can’t see. My wife recently reminded me about the time her keys went missing as we packed up the house for a big move.
