Despite the fact that so many aspects of a modern society rely on the proper and uninterrupted operations of critical infrastructure, security flaws across many industrial control systems (ICSs) are largely vulnerable to cyber-attacks.

Lately, stories of stolen data, compromised systems, and vulnerabilities that send us scrambling to patch, headline the news. It seems that we have been taking two steps forward and one step back when it comes to fighting the battle to protect our systems and networks.

Security threats abound on the internet, which is why ethical hackers and security researchers spend much of their time in search of these issues. As part of the work that they do to keep the internet safe, researchers at vpnMentor announced that they have found an RCE vulnerability in the majority of gigabit-capable passive optical network (GPON) home routers.

Cloud Misconceptions Are Pervasive Across Enterprises

Everyone understands the benefits of the cloud, and the recent iboss 2018 Enterprise Cloud Trends Report shows adoption is increasing, with IT decision makers (ITDMS) planning to increase their SaaS spend from 21% of the overall IT budget to 28% over the next year. Despite this vote of confidence in the cloud from IT, the findings indicate that there is still a fundamental misunderstanding about the cloud that’s creating a disconnect – and misplaced concerns – among office workers and ITDMs.

The cloud is fairly new territory for many organizations and, consequently, it’s an area where mistakes are made stemming from confusion around the role cloud service providers play in security, and how companies should work with them.

Building a new cloud security model

Despite the numerous advantages presented by cloud computing, security is still the biggest factor holding back more widespread adoption by businesses. A recent survey by AlienVault found that an overwhelming 90 percent of organisations are still concerned about cloud security.

Threat actors are leveraging a botnet made up of infected Linux machines to launch powerful distributed denial-of-service (DDoS) attacks against as many as 20 targets per day, according to Akamai's Security Intelligence Response Team (SIRT).

How secure is the hybrid cloud?

The term hybrid cloud is used loosely, which is probably why so many companies say they're planning to adopt it. If you’re planning a hybrid cloud strategy, the security questions you need to think about may not be the ones you’d expect. Hybrid cloud is IT’s flavor of the year. The C-level executives in Avanade’s global Hybrid Cloud study are particularly optimistic: 75 percent believe it should be the main area of focus for their company this year; 72 percent expect to adopt hybrid cloud by 2018; and 76 percent expect the majority of their applications and services – including some critical systems like data and analytics, office applications and customer-facing services – will be running in a hybrid cloud environment within three years.

Rackspace cooking up security-secret-sharing cloud cabal

Rackspace is leading an effort to create a new group of top-tier cloud companies that it hopes will share information about security in close to real time. Rackspace chief security officer Brian Kelly today told The Reg at a Sydney event that he feels cloud companies have to take a lead to address security challenges.

As security teams try to help line-of-business users and other IT practitioners take advantage of cloud benefits as safely as possible, they're increasingly stepping into the role of trusted advisor. The scalability, flexibility, and convenience of software-as-a-service (SaaS), infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS) offerings frequently come at the cost of added risk to the business.

To Secure Modern Networks: Close The Visibility Gap

Modern networks now go beyond traditional walls to include data centers, endpoints, virtual, mobile and the cloud. These extended networks and their components constantly evolve and span new attack vectors including: mobile devices, web- enabled and mobile applications, hypervisors, social media, web browsers, home computers, and even vehicles.
