The old saying goes, there are only two kinds of organizations: those that have been breached and those that will be soon. Clearly, the “moat-and-castle” approach to security has not worked. Simply being “inside” a network – behind a firewall, DMZ and other traditional defenses – does not confer trustworthiness, whether it’s a device, a user, network traffic, or an application.

DHS recently published version 3.0 of the Trusted Internet Connection (TIC) architecture. A response to changing IT conditions, Executive Orders, and OMB mandates, the new architecture seeks to support IT modernization through cloud adoption while keeping security as a top priority. The comprehensive set of documents includes an overview, a catalog of security capabilities, a reference architecture, guidance for pilot programs, advice for service providers, and a very helpful set of use cases relevant to agency needs.

The Threat Risk is a function of likelihood times impact. When it comes to zero-day exploits, particularly those that use return-oriented programming (ROP) or one of its many cousins the likelihood is high, and the impact is higher. How do these attacks work, and what is the industry doing to stop them? More importantly, what can you do to stop them? Is it possible to stop a zero-day without patching or updating systems? Let’s explore these questions. How ROP Works

The Cyberspace Solarium Commission recently released a groundbreaking report detailing 75 recommendations for improving the cybersecurity of the nation, including both the private and public sectors. The Commission, bipartisan in both name and spirit, conducted over 300 meetings with industry, academia, U.S. government, think tanks and foreign governments. I had the privilege of participating in this effort. The result is a comprehensive report that urges immediate and concrete action on its recommendations, organized into six pillars”:

At RSA this year, Chris Krebs gave an important talk: “Cybersecurity Has a Posse” where he stressed the importance of collaboration between government and industry to fight the cybersecurity war. He started by pointing out that his agency, Cybersecurity and Infrastructure Security Agency (CISA) is an “all-source” group. He meant that CISA collects threat information from sources all over the world, including government agencies, private industry, and more. Krebs’ group consolidates that information and disseminates it – daily – to security professionals across all industries.

The security of public sector networks is under attack. Each day security and IT professionals work hard to defend the integrity of mission-critical data and systems against increasingly frequent and complex cyberattacks. Staying informed is critical to staying ahead. That’s great, but there are literally dozens of cyber news outlets, journals, and bloggers to follow. Security leaders and practitioners don’t have time to filter what’s urgent and relevant to their organizations. That’s why we’ve created GovCybersecurityHub.

Many government agencies, particularly large agencies, face enormous obstacles in simply compiling and inventory of the software and hardware under in their system. The difficulty is understandable: I know of one agency responsible for 220,000 makes and models of medical devices (note that this number refers to “makes and models” only. The actual number of devices is much, much higher). In addition, the devices are online intermittently, and many of them are on air-gapped (i.e., physically separate networks), complicating the use of automated tools for identification and inventory.

Every government organization has been the victim of a cybersecurity incident.

Cybersecurity assessment initiatives and frameworks abound in the US government, the most important being the Federal Information Systems Management Act (FISMA), passed in 2002.

Cell phones, tablets, wearables, and other mobile devices dominate our lives. I personally bring my trusty iPad to everywhere, and, like everyone else, have my phone with me at all times.

What are some key methods of protecting them?

Earlier this month, I wrote about the Zero Trust model for security. As I proceed through these daily blogs, I find many of them complement the ZT model; data security is one. Outside the IOT world, the goal of cybersecurity is to protect data. The Zero Trust model recognizes this and focuses on keeping security close to the asset, and portable.

Configuration management is a many-headed beast, but the biggest beast with the sharpest teeth is the patch monster. Every day, a new vulnerability, a new patch – and an old decision: patch and maybe break something (I’m looking at you, Spectre and Meltdown), or stay online and be vulnerable. This model – “panic patching” -- is in wide practice, but not sustainable. For now, an efficient and reliable system is essential; for the long term, we need an entirely new model.

By now, you’ve heard it a hundred times: the perimeter is breaking down, no more “crunchy outside” to protect a “chewy inside”, no more castle-and-moat model of network infrastructure security.

Once upon a time, endpoint security was just a hall monitor: it watched for known bad files identified with a simple signature and sent you an alert when the file was blocked. To be safe, it would scan every machine daily, an intrusive activity that slowed down machines, and sped up the heart rates of affected users and hapless analysts at help desks.

Insider Threat: it’s one of the biggest and most persistent issues in cybersecurity. High-profile cases – Manning, Snowden, and others – have kept the issue in the public eye; government security personnel are rightfully concerned. In addition to the willfully malicious, though, many insiders lack ill intent, but pose a threat just the same.

Do developers at your company keep application security top of mind when coding? Do they have training in secure code development? Do they have the tools to develop code securely?

“Build it in, don’t bolt it on” is a mantra we all learn when we study cybersecurity, yet we see it in practice far too rarely. Our adversaries also know this principle and have begun to implement it by infecting the supply chain – hardware and software – as close to the source as possible. DLT technology partners Crowdstrike and Symantec both note the trend in recent threat reports. In their July,2018 report1, Crowdstrike notes that:

Phishing, vishing, whaling, spear-phishing: the list of clever new terms seems constantly to change. A successful attack by any other name, though, is just as sweet to the adversary. Terminology aside, the fundamental problem is this. Phishing is the most common and effective way to steal data because it goes after the weakest chain in our cybersecurity armor: the human being. Even high-profile people, including one CEO of a major cybersecurity firm and major figures in law enforcement, have fallen victim to phishing attacks.

Every security professional knows that the adversary has the advantage. Security professionals have to find every vulnerability (good luck with that) and remediate it, and the enemy only needs to find one vulnerability and exploit it. This asymmetry underlies their economic advantage: finding one vulnerability gives access to a huge number of systems. In addition, for those willing to forego their conscience and risk jail, it is possible to make large sums of money in a short time, even with a minimum of technical expertise.

You have heard it enough to make you aim a fire extinguisher at your firewall: “compliance does not mean security”.

Once it infects a system, it requires the victim to pay approximately $300 in digital currency (Bitcoin), and immediately tries to find other systems to infect.
