When communications giant Publicis Groupe launched its GDPR compliance project, CISO Thom Langford says, "it was more a case of honing and polishing, rather than building from the ground up," thanks to its existing information security management system and complying with ISO 27001.
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.
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.
Financial services firms write off a certain level of online fraud as a cost of doing business, but these losses directly fund organized crime and help legitimize cybercrime as a career path, says Trusted Knight's Trevor Reschke, who stresses the sector must do more to combat fraud.
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.
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.
As organizations detect more breaches, incident responders are increasingly overloaded, says Darktrace's Dave Palmer, who recommends organizations adopt strategies for "surgically interrupting the bad" while maintaining normal business processes and productivity.
Incident response challenge: How to deliver actionable information to security analysts to enable them to better triage? "The quicker you can detect and respond to an incident, the more you're likely to be able to contain and minimize the risk associate with it," says IBM's Mike Spradbery.
Quantum computing, blockchain, crypto, internet of things: There's a lot of hype around these technology areas, says Jon Geater, CTO of Thales e-Security. So it's essential to pierce the hype and see what's useful and applicable for practitioners.
Running a security operations center today remains a "challenging operation," not only when it comes to the required technology, but also people and processes, says Cyberproof's Adrian Bisaz, who describes how SOCs must evolve.
There's data breach good news and bad news for organizations in Europe, the Middle East and Africa, says Mike Trevett of FireEye's Mandiant. In general, attackers are dwelling in networks for less time before being discovered, except for some particularly long-lasting breaches in EMEA.
The explosion in the growth and diversity of devices linked to networks as a result of the internet of things and BYOD makes it more challenging to manage network security, says Wallace Sann of ForeScout.
