Why is Layered Security Important?

As the name implies, Layered Security involved multiple layers of authentification to reach critical information systems. In the traditional model of overall security, only one layer of defense has been commonly used.  This is most associated with that of legacy systems, especially that with of the Critical Infrastructure, which includes the oil and gas pipelines, water supply lines, the national power grids, nuclear facilities, agricultural and food supply chains, etc.  But as the world becomes more digital and virtual, using just only one layer of security is clearly simply not enough.

Capital  Techies is, one of the top Cybers Security companies in Arlington Virginia that can address your concerns about attacks to your Critical Infrastructure.

How Two Factor Authentication Can Help Your Business

When it comes to protecting an IT and Network Infrastructure and as well as the assets that reside within them, the call for using a Two Factor Authentication (also known as “2FA”) is now being implemented.  In this instance, two layers of security are used.  For example, when it comes to Physical Access Entry applications, very often an employee is now issued a Smart Card which stores their credentials.

After swiping this into a reader, he or she is then allowed into the main point of entry.  In order to gain further access inside the office to other areas, they may have to enter a PIN number on a specialized console.  The same holds true for Logical Access Applications.

With regards to this, an employee will often still have to enter a password to log into their workstation, and use a more specialized device, such as an RSA Fob or even a Biometric device (such as Fingerprint Recognition or Iris Recognition) in order to gain access to the shared folders on the corporate server.

But as technology advances, even this 2FA approach is starting to prove vulnerable.  For example, not only is the Cyberattacker able to break through the first layer of defense, but there are high probabilities as well that they will be able to tear down the second wall defense.  How can a business ensure all of their information and data is safe?

The new answer comes with implementing multiple layers of security, perhaps having as many as four or five layers.  This kind of approach is often referred to as a multi-factor authentication also known as MFA, or “Layered Security” approach.

What Is Layered Security?

Layered Security can be defined by Techopedia as follows:

“Security systems that use multiple components to protect operations on multiple levels, or layers. This term can also be related to the term defense in depth, which is based on a slightly different idea where multiple strategies and resources are used to slow, block, delay or hinder a threat until it can be completely neutralized. Layered security may also be known as layered defense.”

Do I need Multi-Factor Authentication?

As can be discerned from the above definition, the basic premise is that deploying at least three or more layers of defense has a much higher statistical probability of thwarting off a Cyberattacker than just having one or two layers of it.  In other words, the likelihood that a Cyberattacker will reach their ultimate target with a Multi-Factor Authentication protocol will diminish each and every time that they break through a line of defense.  Having as many layers of security as possible is the best scenario for any business or corporation when it comes to protecting their IT Assets, primarily especially that of the Personal Identifiable Information (PII) of their customer base.

It is important to note that theThe  Layered Security approach can be used in both Physical Access and Logical Entry applications. MFA Layered Security is typically much more deployed for the latter scenario, especially when it comes to Network Security.

The team at Capital Techies can set up Multi-Factor Authentication, and is a premier Security Solutions provider here in Arlington Virginia. We can answer any specific questions that you may have about Physical and/or Logical Access entry scenarios.

Do I need Layered Security?

As it has been alluded to earlier, Deploying a Layered Security approach is very important for two reasons:

1.     It can protect the customer base of that organization

2.     It can protect the business entity.

The details of the strategies that need to be implemented in both instances is further described:

Multi-Factor Authentication Strategies for Customer Care

Multi-Factor Authentication for Protecting Confidential Information:

This includes the username and password, as well as any financial information that is transmitted from the customer to the server.  In this case, the use of Secure Sockets Layer (also known as “SSL”) certificates areis most appropriate.

Multi-Factor Authentication for Detecting Fraud:

By utilizing a multi-layer approach instating multiple layers of security, any fraudulent activity that takes place upon arises  unsuspecting customer can be much more easily and quickly  be tracked tracked down, and very quickly.  In this case, using Artificial Intelligence (AI) tools would be of a great strategic advantage.

Multi-Factor Authentication for Message Integrity:

Whenever a customer is signing legal documents electronically, it is up to the receiving party (which is the business entity that is selling the products and services to this customer) must ensure that the documents remain intact during network transmission.  This is also known technically as “Message Integrity”.  In this regard, multiple layers of Encryption and Cryptography security must be used, especially when it comes to safeguarding the electronic signature so that it is not easily forged.

Multi-Factor Authentication for Electronic Communications:

Although the phone option for accessing customer support to an organization remains, the use of Email and chat agents is becoming much more popular for the customer.  In these instances, the messages that are transmitted via both of these mediums must be protected with multiple layers of security, by using the principles of Encryption and Hashing.

Multi-Factor Authentication Strategies For Your Business

From the perspective of the business, there are two very broad types of Cyberthreats that your business they can be exposed to. This makes the case for layered security even stronger for using this a Layered Security approach.

Layered Security for Passive Attacks:

This is when a Cyberattacker tries to tap into and covertly listen into the lines of communications between a business or a corporation, and their respective customers (as well as potential customers) and suppliers/distributors.  This can be done either using a Network based or a Systems based approach.  This kind of attack has been deemed to be one of the most difficult to detect.

Layered Security for Active Attacks:

This is when the Cyberattacker tries to break down the walls of defense of an organization, in order to get access to the IT Assets that reside from within the IT and Network Infrastructure.

It is important that although both threat variants are actively used, it is the latter which gets the most publicity and notoriety.  Examples of this include the Marriott Hotel Group breach, the Target security breach (where millions of credit card numbers were stolen), the British Airways website hack, the Equifax security breach, etc.
