Importance of Attack Surface Mangement (ASM)

RiskXchange - Why attack surface management is important
RiskXchange can narrow your attack surface and prevent threats.

Attack surface management (ASM) is now one of the most important elements of digital defence in the world today. Business leaders, digital defenders and external cybersecurity firms are prioritising ASM to ensure security is at an optimum. Not only does it provide tighter security for your entire business but helps to secure data and important sensitive information.  

An attack surface is quite simply the potential digital gateways through which an attack may occur. The sheer number of connected digital “things” are increasing which means attackers have many more entry points into a network or system. ASM narrows the attack surface and prevents threats. 

What does an attack surface include? 

An attack surface includes things like Internet of things (IoT) devices, email servers, network devices, hidden code from threat actors, partners and other online devices. A good ASM program will be bespoke to any business and know the ins and outs of any cybersecurity plan for your entire company. A full assessment can estimate the risks, pinpoint the entry points and provide knowledge for an adequate defence.  

How can ASM help? 

Attack surface management conducted by a top-tier cybersecurity firm like RiskXchange involves a full assessment of the risks, cutting down on entry points, privileges and access, reducing internet-facing apps and services, running code and more.  

The first stage of ASM includes a thorough assessment of a company’s cybersecurity system and attack surface. Assigning a risk score to all assets comes early on. Reducing the attack surface based on these scores is an important next step. Assets owned by third-party vendors – suppliers, contractors, cloud providers, partners, and others – are also part of the discovery stage.  

There’s also a relatively new risk that comes in the guise of remote workers. Remote work can be extremely complicated and problematic for a business because it adds additional entry points to a network or system. Therefore, opening up an even wider attack surface and creating more risks. This only underscores the need for external cybersecurity firms to continuously monitor a network and provide good ASM. 

Benefits of outlining your attack surface 

Assessing and estimating your company’s entire attack surface not only enables a clearer picture of your company’s cybersecurity needs but also provides a more realistic cost-benefit analysis of each asset. Shrinking your attack surface and applying the resources you have to the remaining surface is the best way of reducing risk and building a strong defence. 

Here are seven key pointers to follow for the best way to reduce your attack surface: 

  1. Simplify and segment your network. 
  2. Reduce, monitor and control your endpoints. 
  3. Combine applications and tools. 
  4. Remove access and permissions when not needed. 
  5. Place deadlines on access. 
  6. Keep on top of staff changes to control access.  
  7. Provide different levels of security for privileged access.  

All of the above must be part of a continuously monitored program that will keep you on top of cybersecurity at all levels of a business. ASM is an ongoing program that includes discovery, inventory, risk analysis and more. Real-time attack surface insight is key to reducing risk and bolstering security.  

ASM as part of best practices in cybersecurity 

ASM should become part of workplace culture and a mindset adopted by the entire company – not just by those in IT departments and leadership roles. Staff should be educated and made aware of the risks, especially those working remotely which can theoretically put the whole company at risk.
