But what is Attack Surface Monitoring?
Every software when developed has certain entry points i.e.: loose ends, placed both advertently and inadvertently, that can be used to gain unauthorized or backdoor access (depending upon your intentions) to the application’s database and manipulate it according to your intentions. These entry points are referred to as ‘attack surface’ and can both be a menace as well as a blessing in disguise to gain access to a system.
Attack surface monitoring involves an active review and analysis of programs to identify such possible points of entry so that they can be appropriately addressed to make the program as secure and air-tight as possible. It can actively reduce the possible risks that an application of the modern-day may face and provides developers with opportunities for optimization with improved code.
What compromises the Attack Surface?
Attack surface might feel like a software-related term that has something to do with the lines of code which comprise the application. Attack surfaces are much broader than what one might generally think.
An attacks surface comprises of the following three components:
- Physical Attack Surface The physical attack surface includes all potential points of entry that can be physically accessed to enter into a system or a network. These include computers connected with the system, servers, laptops, modems, access points, routers, printers, and even security cameras that can serve as the most convenient physical attack surface. These when coupled with a sold-out employee can make a destructive combo that has the potential for a disaster any time of the day.
- Social Attack Surface Humans are social beings; they cannot help but interact with hundreds of people daily without even realizing they have done so. In addition to this, the human mind is not programmed like some lines of code that devise a certain line of action in a certain circumstance. The way it functions is a wonder in itself but it can be tricked into performing actions that might not opt had it been more aware of the situation. Employees at organizations can get stalked in public places and may end up casually leaving a loose end for a potential breach e.g.: a person watching over your shoulder can see your password as you type it to log in to your laptop and see an update about an upcoming meeting during your coffee at Starbucks. It demands vigilance and skepticism to be on your toes at all times so you do not end up letting any make a fool of you.
- Digital Attack Surface As our original expectation was, the digital attack surface is indeed the opportunity embedded within the software that can be a possible point of intrusion. These include virtual points of intrusion that can be used to break into the system. Digital attack surfaces include servers, websites, databases, applications, cloud networks, and even operating systems.
How To Reduce Your Attack Surface
If you are thinking, ‘all of this is quite messed up, what should I do’, then we share the same thoughts. Here are some tips and tricks that might come in handy and save you from trouble. Of course, the inherent nature of software is such that it is impossible to eliminate all risks, but you can follow a few best practices.
To avoid intrusion from a physical attack surface:
- Establish access controls over different levels of hardware concerning their vulnerability e.g.: a person from the billings and finance department does not access the server room. Similarly, a newly hired IT assistant should not be allowed unmonitored access right away. This is not to say that people are dishonest. This is just another ‘better safe than sorry’ measure.
- Advise employees and users systems to be aware of their surroundings and to opt for practices that are safe and steer them away from trouble e.g.: leaving your passwords on a sticky note at your desk is just carelessness, avoid it at all costs.
The reality that a social attack surface exists means you have to be cautious:
- It is best if you can avoid using your laptop computers in the public but when you do not have a choice, try to use them in a place with minimum activity. Try to be in a position where no one can look over your shoulder (you ever who is stalking you, when and where) and NEVER leave your device unlocked and unattended.
- Social interactions are part of what makes us human. Beware that some person you met at the party who seems to be more interested in your job than you, could be a criminal mind who is after your and your company’s money and not a potential candidate for your future friend.
Physical and social attack surfaces are inherently risky but they can seldom result in a big problem without the digital attack surface. In the end, it is the systems and the databases that the devious minds are after. Digital attack surfaces although require greater intricacies for protection, some measures do belong to everyday usage and should at all levels:
- Do not plug-in unknown devices into your laptop or computer especially if it is a USB stick or a memory card you found by the doormat.
- Be careful with your online activity, there are phishing links and devious sites scattered all over the internet. No matter how enticing the offer is, if you are not sure about the website’s safety, stay away.
- VPN services are available for prices as low as $2.49 a month and support even more than 5 devices at a time. Something even this cheap can add layers of protection between you and a potential risk so why not invest in time and save yourself from the hassles.
- Get your systems reviewed for attack surfaces periodically from ethical hackers and digital security experts. They can then devise security patches for your software and make it safer for usage in the future.
Now all of this might seem intimidating, scary, and try to shatter one’s trust in humanity but it is quite the contrary. Some of these measures might feel too trivial to even care about but it is the collective effort to follow these practices that will guarantee better security for all individuals in the ecosystem and the entire internet at a broader scale.
Advanced Attack Surface Monitoring
The field of cybersecurity is a continuously evolving field of study where things change as quickly as drinking a cup of coffee. It is not just that you need to have all fronts covered and have strategies in place that you have learned from past battlefields but also stay one step ahead of the malicious mind who might try to take advantage of you.
This demands all the help and skill that you can acquire to secure your fort from all fronts. Do not just bar the gates, have soldiers at the windows and another set of soldiers in the hallways to contain the intrusion in case of a misfortune happening.
Attack surface monitoring tools can be a great help in this matter. They are specially developed by individuals who are well-aware of the latest tactics in the market being used by hackers to fulfill their evil desires.

As it is an open source system, the code is frequently tested and enhanced by volunteer developers. These enthusiasts also create plug-ins for the system that extend its capabilities to scan specific technologies without altering the core code. There is a large library of these plug-ins and getting to know them all and how to integrate them into the program makes this tool difficult to use.
The Zed Attack Proxy is a software package that will install on Windows, macOS, and Linux. You can download ZAP for free from the project’s website.
Who is it recommended for?
This is a tool for use by penetration testers. You need to spend time to get to know how to use the tool effectively, and once you have acquired that knowledge, you have a marketable skill that would be put to more efficient use as a consultant than as an IT department technician. Infrequent use can mean you have to relearn the tool every time.
Pros:
- Attacks are implemented by activating a free plug-in
- Can be used for intelligence gathering
- Includes a scripting language
Cons:
- This is not an automated monitoring system but a penetration tool
8. ImmuniWeb
