Vulnerable vs. Exploitable: Why These are Different & Why it Matters

Vulnerable vs Exploitable Blog Banner.png

Pop quiz: What’s the difference between vulnerable and exploitable?

As we’ve written before, a vulnerability is a weakness in a software system. And an exploit is an attack that leverages that vulnerability. So while vulnerable means there is theoretically a way to exploit something (i.e., a vulnerability exists), exploitable means that there is a definite path to doing so in the wild. Naturally, attackers want to find weaknesses that are actually exploitable. As a defender, being vulnerable isn’t great, but you should be especially worried about being exploitable.

There are a few main reasons why something that is theoretically vulnerable is not actually exploitable:

  1. There may be insufficient public information to enable attackers to exploit the vulnerability.
  2. Doing so may require prior authentication or local system access that the attacker does not have.
  3. Existing security controls may make it hard to attack.

 Below, we’ll explain why this matters and how you can use it to improve your security posture.

What You Need to Know About the Apache Struts Vulnerability

by Anthony Alves , posted in HIDS, Apache Struts Vulnerability, Host Intrusion Detection System

Apache Struts Blog Banner.png

New vulnerabilities are discovered on a regular basis, and some receive quite a bit of publicity, while others fly under the radar. The latter situation can open up extensive opportunities for attackers to exploit these vulnerabilities.

A good example of one that has been “out” for quite a while without receiving much attention in the media (and thus from organizations that may be affected) is the Apache Struts vulnerability. Today, we’d like to take a look at what it is, why it’s worthy of attention, and what you can do to protect your organization.

Why Automated Security Threats are Proliferating and How to Fight Back

by Anthony Alves , posted in Cloud Security, Automated Security Threats

Automated Security Threats Blog Banner.png

We’ve written before about the importance of looking inward, rather than out, when it comes to evaluating what types of cyberattacks are the biggest threat to your unique organization. A large part of the attack landscape today includes automated threats. Rarely do we come across handcrafted attacks targeting specific organizations. A far cry from bespoke and laser-targeted, the vast majority of today’s cyberattacks are built for volume and trolling for the weakest point of entry.

So, what exactly are automated security threats and how can you best protect your organization from them?

Considerations For Creating Secure User Groups on AWS Using IAM

by Anthony Alves , posted in AWS Security, IAM, Identity Access and Management, IAM Users and Groups

AWS IAM Blog Banner.jpg

A big difference in the way on-premise infrastructures and cloud infrastructures are implemented centers on the way that user permissions are assigned. As you move towards software-defined everything, where data and systems are far more connected (generally a good thing), you need to pay special attention to the roles and permissions you grant to ensure that users are only given as much access as they absolutely need. No more, no less.

How to Verify That Compliance Controls and Processes are Being Met

by Anthony Alves , posted in Cloud Security, Compliance, Compliance in the Cloud, Compliance Strategy

Compliance Controls and Processes Blog Bannerv2.jpg

Compliance is a complex, ongoing process. Between deciphering requirements into relatable terms, allocating a budget, and  assembling a team for your compliance audit — all while trying to stay focused on running your business — there’s a lot to think about and do. And after all of this, there is still more that needs to be managed.

From regular maintenance of the processes, controls, and technology you implemented, to questions from customers about your level of compliance, you’ll quickly realize that compliance is a continuous process that needs to be managed, not a one-and-done activity.

Having said that, what are you doing, or going to do, to make your compliance plan accessible so team members — from Security to IT to Sales — can quickly verify a control or process?

Compliance_Series_Part_11_Blog_Banner.jpg

When companies prepare to meet compliance, whether it’s PCI DSS, HIPAA, or SOC 2, one thing that can be estimated inaccurately is the stakeholders who need to be involved — who they are, what departments they come from within your organization, what their roles are, what knowledge and skill sets they require, how long they’ll be needed, etc. This post is intended as a practical guide to help you develop a thorough and realistic resource plan for your next compliance audit.

When is Good Enough Good Enough? Meeting Compliance Without Losing Your Mind

by Anthony Alves , posted in HIPAA, Compliance, Compliance in the Cloud, PCI DSS

Compliance_Series_Part_10_Blog_Banner.jpg

Have you heard one about the bear and the two hikers?

A bear jumps out of the bush and starts chasing two hikers. They both start running for their lives, but then one of them stops to put on his running shoes.

The first hiker says, "What are you doing? You can't outrun a bear!"

The second hiker replies, "I don't have to outrun the bear; I only have to outrun you!"

Compliance works in a similar way. You don’t need to be the most compliant company; you just need to meet the requirements well enough to satisfy regulators, auditors, customers, and stakeholders. And, ideally, you want to be more compliant than your competitors. That’s how you outrun the bear (err… win the customer.)
