Does Your Network Need A Watchman?

Introduction 

You have decided to open a bar. For that, you hire the best decorator, make the selection of the best bottles imaginable, hire the best bartenders that you can hire. 

The bar opens with a lot of buzz in the market and instantly becomes the hottest spot in the town.

And within a month it’s closed!

As it turns, allowing anyone to go in and out of the bar isn’t a sound business practice. The same goes for cybersecurity. Imagine your content having no visibility into a common source of problems and non-compliance.

This may be the case, but many businesses still don’t make the inspection of encrypted traffic their priority.

Let’s Begin 

Let’s start with understanding encrypted threats: to put it simply, Secure Socket Layer makes an encrypted tunnel for securing data over the internet connections. 

However, Transport Security Layer is the latest version of SSL. While both of them provide legitimate security benefits for web sessions and internet connections, cybercriminals are using these encryption standards to hide malware.

As per some reports, 35% of threats are encrypted, and the number is still rising. The saddest part is that there is a fear of complexity and a lack of awareness of the need to inspect SSL and TSL traffic.

This way of dealing committed by many people is dangerous because traditional security controls lack the capability to process power to detect, inspect, and mitigate cyberattacks through HTTPS traffic.

According to our perspective, hiring a watchman would have made all the difference to be successful and having to shut down due to insufficient control over traffic.

As the rate of encrypted threats continues to increase, examination of the encrypted traffic could make a difference in recognizing and blocking the threats.

Imagine your bar had a dress code, and regardless of it, without a watchman or doorperson, there’s nothing to enforce it. No one to check the coats; you will be unable to see whether someone is wearing a hockey jersey or crass political T-shirt.

The interplay between content filtering and encrypted traffic is identical. Now, around 80 to 90 percent of traffic comes over encrypted connections by using HTTPS; your content filtering becomes completely inaccurate.

They have limited efficiency when it comes to the identification of the destination webpages and deciding how to deal with potential threats. Also, without the ability to what’s going on below the surface, you are in danger of threats that were sneaking in the past.

Sandboxing solutions are also of limited use when it comes to encrypting threats. If a cybercriminal manages to place an encrypted connection between the threat actor controller and an endpoint, they could send files back and forth.

In many cases, organizations have a single sandboxing solution, which has the potential to scan all the files and ensure that they are non-malicious before allowing them.

If communication is encrypted, the sandbox solution is of no use because you will be unable to capture the files travelling between a CC and endpoint.

Though the solution can see encrypted traffic happening between two IPs but can’t get what’s going on. For example, think of your watchman as a seasoned professional.

He has got a list of troublemakers 20 years in the making and can spot one mile away. Without someone at the door to recognizing those who become a danger to themselves and others.

They can walk in straight, and to someone whose job does not include spotting these troublemakers, they are just another patron.

Many security solutions are designed for preventing data loss, but encryption has the ability to hide this entirely. This permits malicious actors to steal private or confidential data without anyone noticing them.

Once they have enough to blackmail you, they will deploy ransomware. Normal gateway appliances without decryption turning on have no visibility into this traffic.

Moreover, it extends beyond trojans, ransomware, and malware. Such data exfiltrations can also put you out of compliance with regulations like PCI or GDPR. Did your bar close because patrons were seen leaving with drinks? That isn’t illegal for them but for you.

Sometimes the penalties for lack of compliance, whether its local ordinances for pubs or national compliances, can threaten or even close a business. 

The answer is the same in both cases: an effective defender who is smart enough to know whom to permit to enter and the muscle to back it up without creating a scene at the door.

By now, it must have been clear to you whether a watchman for your network is essential or it’s fine without him.
