If you happen to be a cybersecurity specialist, you are possible acquainted with the sea of acronyms our sector is obsessed with. From CNAPP, to CWPP, to CIEM and all of the myriad other people, there appears to be to be a new initialism born every single day.
In this article, we are going to search at another trending acronym – CTEM, which stands for Continual Risk Publicity Administration – and the generally-astonishing worries that come together with seeing a CTEM program via to maturity. While the strategy of CTEM is not manufacturer spanking new, obtaining produced its in-print debut in July of 2022, we are now at the place in which numerous organizations are starting up to try out to operationalize the programs that they have been location into movement in excess of the past number of months. And as corporations start to execute their thoroughly developed plans, they may well discover them selves bumping up towards some unexpected issues which can guide to setbacks.
What is Constant Threat Publicity Management (CTEM)?
But initially, to backtrack, let’s just quickly critique what CTEM is and is just not.

Continuous Threat Exposure Management is not a technology and you won’t be able to go to a vendor in hopes of finding a CTEM alternative (or, at minimum not with just just one single resource). What CTEM is, rather, is a continuous 5-stage plan or framework meant to assist organizations check, evaluate, and decrease their degree of exploitability and validate that their evaluation and remediation procedures are optimum. According to a Gartner® report, “The goal of CTEM is to get a consistent, actionable security posture remediation and improvement plan that company executives can fully grasp and architecture teams can act on.” (Gartner, 21 July 2022, Put into practice a Ongoing Risk Publicity Management (CTEM) System)

What are the Aims of CTEM?
The Gartner report even further states, “Technology-centric attack surfaces and vulnerability self-evaluation jobs produce hardly ever-actioned reports and extensive lists of generic remediations. Vulnerability management applications almost never retain up with the aggregate volume of their have corporation, major to rapidly expanding attack surfaces”. (Gartner, 21 July 2022, Apply a Continuous Threat Exposure Administration (CTEM) System) These elements, coupled with some other critical motorists, this kind of as the problem in sustaining security posture more than time amid an ever-mushrooming attack surface area, necessarily mean that classic solutions for holistically ensuring security are growing a lot less helpful all the time.
According to Gartner, “The objective of CTEM is to get a reliable, actionable security posture remediation and enhancement plan that business enterprise executives can comprehend and architecture groups can act upon.” (Gartner, 21 July 2022, Apply a Ongoing Menace Exposure Administration (CTEM) System). When correctly carried out, CTEM can help businesses regularly strengthen their security posture by identifying and remediating most likely problematic parts before they can be leveraged by attackers.
3 Challenges on the Highway to Assembly CTEM
Magnificent. So what are you waiting for?
Hold up environment up a CTEM method is a excellent initiative – but there are some difficulties in implementation that want to be resolved in get for execution to be successful. Accounting for them earlier on in the implementation phases could conserve time and frustration down the road.
Challenge 1 – Getting non-security and security on the same webpage
It can be a well-recognized point that IT/infrastructure/DevOps/application, and so on. teams and security teams do not usually communicate the same language this is problematic in a lot of strategies but when implementing new plans or undertakings, this disconnect can grow to be even a lot more problematic. In implementing CTEM, this can translate into a deficiency of knowledge of who from the non-security crew owns what, and not getting aligned on SLA expectations, amongst other issues.
The problem here is that totally speaking the will need is challenging, specifically when groups are bogged down with loads of “URGENT!” assignments – and, to them, CTEM is just one more 1 of people jobs. This lack of comprehending can disincentivize them from essentially undertaking what demands to be performed.
How to repair – From the really earliest phases, deliver stakeholders from non-security teams into the discussion. It is really not superior more than enough just to present them with a to-do record. Instead, sit with them and make clear the objectives you’re attempting to attain so that they have a good knowing of what is currently being done. Request for their enter and uncover out what they will need to have from you or other teams in the business to make their life much easier. Also, sharing cyber attack news with them will make them extra aware of the business enterprise effects that they could have, and how it truly ties back into their portion of the business.
Challenge 2 – Looking at the bird’s eye see
A thorough CTEM system covers many unique spots, from Cloud, to Ad, to software program vulnerabilities, to network security and essentially all the things else. Every single a single of these exists in its personal silo and has its have proprietors, their very own tooling and their personal checklist of issues to take care of. The intention of CTEM is to unite all of them into a single holistic see with all areas informing the other individuals. In practicality, that indicates aggregating all data and utilizing it to understand priorities and responsibilities.
But acquiring a baseline of understanding is tough as just about every of these areas necessitates diverse experience. The final thing you would want is to have a application that has been painstakingly built and executed but fails to fully grasp the challenges that each individual location provides – or worse, forgets to consist of any certain location of issue.
How to resolve – Determine someone as the “position individual” – the one person who can take the bird’s eye check out and turn out to be a high-level master at knowing how all the coated places converge and impression just about every other. This particular person isn’t going to want to realize the tiniest bits and bites of how each and every device will work or what each and every class of security issue encompasses, but they need to be ready to grasp the entirety of the massive image so they can thoroughly and accurately be certain that all areas are accounted for and are getting continually addressed by professionals who do have deep and nuanced skills.
Problem 3 – Overcoming diagnostic overload
Back again to that point about all the unique areas protected in CTEM Yet another vital part to notice is that as they all have their own resources, they all produce alerts. And so even though a primary objective of CTEM is to streamline all of the data stemming from these equipment, just one noteworthy byproduct is just a full ton of extraneous noise.
How to resolve – Accept the point that correcting every thing is fairly a great deal difficult, which means you require to prioritize and be as successful as doable. To do this, concentrate on the scopes and exposures that could most probable be exploited by an attacker and which could direct to the finest business enterprise effects. It may well assist to consider the “crawl, stroll, operate” tactic, i.e., begin with newborn ways which zero-in on a compact scope and enlarge it as your application grows far more mature. (Want to make assembly CTEM even simpler? Get this checklist on practical ideas to streamlining CTEM in this article.)
Conclusion
According to Gartner, “By 2026, companies prioritizing their security investments based on a constant exposure management programme will be a few moments considerably less probably to suffer from a breach.” (Gartner, 21 July 2022, Employ a Steady Risk Exposure Administration (CTEM) Software) And we truly feel that is big. Hopefully, by ironing out some of the opportunity kinks together the way, your firm will be primed to fulfill CTEM seamlessly.
