Hacking is no longer an ‘outside game only’ in modern times.
The insider threat is growing at incredible pace. It has lately thrown a number of organizations under the bus with them reviewing and fabricating a whole new set of security practices to prevent such a thing from happening. Old grudge or malicious intent, it’s almost scary knowing how any of your trusted employees could against you for some impressive cash.
But that comes as a treat for the hackers. Who wouldn’t be delighted to know that with insiders under their wing they need the minimum of resources to conduct a cyber breach? It’s like getting the ripest and most delicious fruit without moving a muscle. Well, you have to utilize your brains, but that’s the bare minimum amount of work you need to get the insider credentials.
You may resort to encryption and a series of other powerful cyber security weapons but with insiders at work, detecting them becomes almost an impossible task. This is why you need to adopt to a system that other than providing an online security, could keep a close eye on the working pattern of the employees. A machine learning system that doesn’t follow strict rule-based detection techniques to spot anomalies.
You need behavior analytics systems.
What are those? How do they work? Let’s learn more about them.
What is User and Entity Behavioral Analytics (UEBA)?
User and Entity Behavioral Analytics, as the name suggests, works basically on collecting and assessing users behavior, compare them with the past data, and pull out any anomaly prevailing. This system can aptly help enterprises get a transparent insight of what’s currently happening inside the premises and dig out any risky activities in real-time.
This system mainly utilizes machine learning to learn normal behavior of an entity from the initial feeds. You provide the system some baseline behavioral patterns so they can detect any future anomaly in record-time. It actually works when encryptions are compromised as a result of an outsider posing as an authorized user or a malicious insider attempt.
The UEBA system continually keeps upgrading, adapting new modules, working pattern, entity behavior and analyst inputs to be on track with new anomalies identified.
Why Behavioral Analytics is the Best Bet for Enterprise Cyber Security
We all look for a cyber security option that can assist us effectively in multiple ways. We all look to secure our enterprise with a number of security layers so if one fails we will still have many others protecting our crucial data. This multi-layered system becomes even more important with most of our information being up on the cloud. One wrong move and it can cost millions of hard earned money.
While making several copies of your data, encrypting and locking them is a nice option, it might not save us from insider threats. This is why a behavior analytics system is mostly preferred by enterprises who have suffered before or are quite vulnerable to such an incident.
UEBA helps an enterprise:
- Prioritize alerts on the basis of the baseline instructions.
- Get user-level and entity level insights on who is using the data, when and from where.
- Detect and issue a warning against slow, multistage attacks.
- Record-time detection and diversion of privilege access misuse.
- Assess and raise warning signs for multiple login failures or an IP location anomaly.
- Detect credential violations (Password sharing, access device sharing).
- Assess user entities to detect possible valuable asset exploitation.
- Identify any machine-to-machine hopping attempts by the hackers.
- Recognize and divert any abnormal resource sharing attempt like downloading or uploading too many sensitive files in one go.
- Uncover any protocol anomaly
- Put a stop on any credential theft attempt
- Distinguish normal emails from spear-phishing ones to control account compromise incidents.
- Detect any anomaly in the traditional security systems including firewalls, antivirus, antimalware software.
Things to Keep in Mind While Deploying a UEBA System
Now when you have decided to opt for the ever reliable Behavior Analytics system, it’s safe to explain a list of points that can better its effect. They include:
- Just like every other security system UEBA systems need certain external feedings in order to work to an enterprise’s requirements. Other than the customized baseline feedings, make sure you keep updating the feeds in accordance with the latest trends and environmental changes. You are allowed to mold the rules and alerts in sync with your enterprise’s norms.
- Employee training is just as important. There is no need to deploy a complex system when your employees cannot identify the warning signs.
- Think whether you want the system to be host-based or network-based or both on the basis of your requirement.
- Budget. Provide a specific and completely apt budget to get yourself a UEBA system. Your expenditure should be completely in sync with company’s policies.
- Is it the correct time to deploy it? Is your IT systems updated to adopt such a change? Consider these important questions before availing such a service.
Behavioral analytics is important. We have come to know about this by now. From incident diversion, threat hunting to providing a complete transparent insight of your company, its success rate is what makes UEBA a top-choice in the cyber security field.
