How microsegmentation can deliver zero trust security [Q&A]

Red and blue security padlock

With a never-ending supply of new security threats presenting themselves every day, it can be tough for IT departments to keep up.

While perimeter security continues to be important, the sheer volume of novel attacks means that, eventually, an attack will bypass defenses and gain a foothold in the interior. To harden the network interior, best practice now calls for microsegmentation to achieve a zero trust environment, but that’s not easy to do.

Do IoT devices really pose a security risk, or is it merely paranoia?

IoT devices

Market data firm Statista projects that by 2025, there will be 75 billion IoT devices in use. Smart devices are now found throughout most commercial offices, yet a lack of security could make them ticking time bombs. IoT devices often come with security shortcomings, and it can be difficult to detect when someone has exploited one of their vulnerabilities.

Why are IoT devices dangerous? It's not a single issue; rather, it's intrinsic to the way that the technology itself works.

The changing landscape of cybersecurity

Bad actors have been seeking opportunities to take advantage of unsophisticated netizens or unprotected organizations since the dawn of the World Wide Web, but today’s bad actors are in a class by themselves. Nation-state actors, often operating through a vast network of well-funded proxies, strive to exert influence, threaten stability, and sow discord through the mechanisms of cyberspace. Hacktivist organizations seek to undermine, damage or discredit organizations whose agendas and politics they oppose.

They may not be as well funded as nation-state actors, but they are populated by technically sophisticated people who have bought into a cause -- and when these people work together, they can pose serious threats to those with whom they disagree.

Half of security professionals who adopt a more traditional or reactive approach to their data protection and security don't believe they will reach their digital transformation goals in the next five years.

This is among the findings of a report from data protection company TITUS which conversely finds that nine out of 10 security professionals deploying a strategic approach believe their current efforts will address digital transformation needs within five years and that their organization would achieve its digital transformation goals in the same timescale.

UK age verification rules could put users at risk

identity verification

With age verification checks for users of adult sites in the UK set to come into force this summer, cyber security company F-Secure says that the new rules could increase the risk of identity theft and other cyber crimes.

Under the new laws, British internet users will be required to verify their age in order to access adult content websites. This could be by sharing personal information such as passport, driving license, phone number or credit card details with third-party age verification platforms, or by buying a 'porn pass' at a store.
