Driven by the EU's General Data Protection Regulation and other regulations, as well as the move to the cloud, more organizations are turning to data classification to help them silo and protect their most sensitive information, says Tony Pepper, CEO of Egress.
The EU's GDPR is already having an impact on how organizations approach data breach detection and remediation, leading many to rely more strongly on security orchestration and automation, says Allen Rogers of IBM Resilient.
Organizations are increasingly turning to devices and the cloud to foster better collaboration and access to essential data. But as they do so, "the number one blocker for enabling digital transformation is security," warns BlackBerry's Florian Bienvenu.
Organizations are increasingly tapping behavioral analytics to help incident responders "correlate data from multiple sources and save time in the response workflow" - in other words, to more quickly detect and mitigate breaches, says Nick Bilogorskiy at Juniper Networks.
Never underestimate the human factor in attacks. Indeed, many of today's top attacks - from malware to phishing - require some level of interaction from victims. "They're targeting people - they're targeting the users within our businesses," says Proofpoint's Adenike Cosgrove.
Attackers continue to shift their tactics to help evade improvements in defenses, says Rick McElroy, security strategist for Carbon Black. Recent trends include fileless attacks, shifting from PowerShell to WMI, plus cryptojacking and credential harvesting.
To increase the effectiveness of security information and event management tools, while lowering the rate of false positives, organizations need to bring in more context about user behavior, says Derek Lin of Exabeam.
We need to talk about ransomware, says James Lyne, global research adviser at Sophos: "It's not the big, sexy security topic that it once was, but there's some really interesting evolution in their tactics." Lyne rounds up the latest tactics and describes how machine learning is offering new defensive hope.
Recent failures of IT systems at some major airports and banks are a reminder that as an organization launches a digital transformation project, or seeks to move more of its processes to the cloud, those efforts won't necessarily proceed smoothly or securely, says Skybox Security's Justin Coker.
To stop malware, it helps to spot it as fast as possible and keep tabs on what it might be trying to do. "We all know that a well-funded, patient, creative attacker - there's no way to keep them out," says Lastline's Patrick Bedwell.
The latest challenge to face CISOs: Finding the best way to keep their organization secure while at the same time navigating political edicts that may lack any technical detail or present solid facts or alternatives to suspect technology, says Jaya Baloo, CISO of KPN Telecom.
For attackers, "credential stuffing" - using stolen usernames and passwords to log into any site for which a user reused their credentials - is the gift that keeps on giving, says security researcher Troy Hunt. Here's how organizations can mitigate the threat.
In the past 12 months, there's been a blistering series of high-impact attacks that increasingly blur the lines "between statecraft and criminal organizations," says CrowdStrike's Zeki Turedi. How much of this blurring is intentional?
Email attacks continue to bite businesses, with organizations reporting not only a steady stream of ransomware, but also increasingly targeted social engineering attacks and account takeovers for cloud service users, says Barracuda's Hatem Naguib.
As the prevalence and scale of data breaches continues to increase - with attacks such as WannaCry and NotPetya having compromised entire business sectors - organizations must focus much more on preventing attacks, says Check Point's Gad Naveh.
