Many security teams are overwhelmed with the scale and ferociousness of digital threats. Threats are sneakier and more damaging, and security operations centers (SOCs) are being worn down investigating and stomping out incidents.
As enterprises migrate to the cloud, strong perimeter defenses are not enough to stop cyber attackers from infiltrating the network. Together, Gigamon and Vectra enable organizations to gain network visibility and automate threat management - providing continuous monitoring of network traffic to pinpoint cyber attacks that evaded perimeter defenses.
Chris Morales, Head of Security Analytics at Vectra joins us to discuss what challenges he sees customers facing when moving to Amazon Web Services (AWS) and how Gigamon and Vectra can help them.
Attacks never really go away
Many enterprise organizations are currently evaluating the Vectra Cognito platform, and over the past weeks, several customers detected WannaCry attacker behaviors. Just because the headlines stopped, doesn’t mean that the attack did.
WannaCry was first reported by the media in May of this year and we had customers who detected and responded to outbreaks within minutes. A couple of days after the initial impact, it was reported that stopping the WannaCry command and control server limited the effectiveness of WannaCry in the wild. While that may have been be true, organizations are still detecting instances of WannaCry within their enterprise networks. While this is a smaller scale than the attack in May, it is important that enterprises continue to monitor their networks for what is proven to be a fast propagating ransomware attack with the potential to cause damage very quickly.
In the fight against cyber-attacks, time is money. According to the Ponemon institute, the average cost of a data breach is $3.62 million. Reducing the time to detect and time contain an incident can significantly mitigate the cost of a breach, and possibly prevent it.
Maturity level and effectiveness are two of the most important measurements of SOC performance. Maturity reflects an enterprise’s development level regarding its approach to managing cybersecurity risk, including risk and threat awareness, repeatability, and adaptiveness. Effectiveness is a measurement of the SOC’s ability to detect and respond to an incident as it happens.
We conducted a survey.
The European Union (EU) General Data Protection Regulation (GDPR) is set to come into force on 25 May 2018. However, many IT, security and compliance leaders in the EU and globally still have a long way to go before they can truly describe themselves as "GDPR-ready." Artificial intelligence (AI) can make valuable contributions toward GDPR preparations and operational compliance.
We are seeing another outbreak of ransomware that appears to be a combination of previous other ransomware campaigns. As is always the case, criminal gangs learn from each other.
Petya was successful in 2016 using email attack campaigns and a ransomware-as-a-service business model. Wannacry introduced new worm propagation techniques proving highly successful in hitting thousands of systems in a short time span last month.
Cisco recently announced the term “intent-based networking” in a press release that pushes the idea that networks need to be more intuitive. One element of that intuition is for networks to be more secure without requiring a lot of heavy lifting by local network security professionals. And a featured part of that strategy is Cisco ETA:
"Cisco's Encrypted Traffic Analytics solves a network security challenge previously thought to be unsolvable," said David Goeckeler, senior vice president and general manager of networking and security. "ETA uses Cisco's Talos cyber intelligence to detect known attack signatures even in encrypted traffic, helping to ensure security while maintaining privacy."
Earlier this month Vectra announced plans to leverage the capabilities of VMware NSX to accelerate the detection and mitigation of hidden cyber attackers in virtualized data centers.
Vectra currently applies artificial intelligence to automatically detect attacker behaviors inside virtualized data centers. Vectra also integrates with endpoint and network response tools to automate the workflow.
Vectra Networks last week published the 2017 Post-Intrusion Report, which covers the period from January through March. While there are plenty of threat research reports out there, this one offers unique insights about real-world cyber attacks against actual enterprise networks.
Most industry security reports focus on statistics of known threats (exploits and malware families) or give a post-mortem look back at breaches that were successful. The first one looks at threats that network perimeter defenses were able to block and the second lists attacks that were missed entirely.
Vectra Threat Labs analyzed the WannaCry ransomware to understand its inner workings. They learned that while the way it infects computers is new, the behaviors it performs are business as usual.
WannaCry and its variants behave similarly to other forms of ransomware that Vectra has detected and enabled customers to stop before experiencing widespread damage. This is a direct benefit of focusing on detecting ransomware behaviors rather than specific exploits or malware. Many of WannaCry’s behaviors are reconnaissance and lateral movement on the internal network, within the enterprise perimeter.
