The Importance of a Layered Approach in Cybersecurity

January 30, 2023 written by Cole Smith

Cybersecurity has become a top priority for individuals, businesses, and governments alike, with the
number of cyber-attacks increasing every day. While antivirus software has been the go-to solution for
many years, relying solely on antivirus is no longer enough to protect against today's sophisticated cyber

Here is why you need a layered approach to cybersecurity:

1.  Antivirus only focuses on known threats.

Antivirus software works by detecting and removing known viruses and malware. However, it
can't protect against new, unknown threats that have not been added to its database. Hackers
are constantly developing new methods to bypass antivirus software, making it more
challenging to protect against these threats.

2. Antivirus can only protect against certain types of threats.

Antivirus software is only effective against specific types of cyber threats, such as viruses and
malware. It cannot protect against more advanced threats such as phishing attacks, SQL
injection, or DDoS attacks.

3. Antivirus can slow down your computer.

Antivirus software runs in the background and continuously scans your system for threats. This can put a strain on your computer's resources, slowing down your device's performance.

Onion Layers of Security

A layered approach to cybersecurity helps protect against a wider range of threats by combining
multiple security solutions to create multiple layers of protection. Here are some of the components of a
layered cybersecurity approach:

1. Firewall

A firewall helps protect against unauthorized access to your network by monitoring incoming
and outgoing network traffic and only allowing authorized traffic to pass through.

2. Antivirus and Anti-Malware

While antivirus software alone is not enough, it's still an important component of a layered
approach. Antivirus and anti-malware software help detect and remove known viruses and
malware from your system.

3. Email security

Email is one of the most common ways for cyber attackers to deliver threats. Email security
solutions such as spam filters and anti-phishing tools help prevent phishing attacks and other
email-based threats from reaching your inbox.

4. Network security

Network security solutions, such as intrusion detection and prevention systems, help monitor
and protect against network-based attacks, such as DDoS attacks.

5. Data backup and disaster recovery

Data backup and disaster recovery solutions help protect your data and keep it safe in the event
of a data breach or disaster.

6. Multifactor Authentication

Multifactor authentication, such as Duo, can help protect networks and programs with
additional authentication steps. MFA (Multi-Factor Authentication) is becoming almost standard
in any environment.

7. Security Awareness Training

Your biggest defense is having a solution in place to train your employees. For the emails that do
get through a spam filter, making sure your employees are trained on what to look for is usually
overlooked, but the biggest investment in having good cyber hygiene.

In short, relying on antivirus software alone is no longer enough to protect against today's complex and
sophisticated cyber threats. Combining multiple security solutions, a layered approach to cybersecurity
provides a more comprehensive and effective defense against a wider range of threats. Investing in a
layered approach to cybersecurity is essential to keeping your digital assets and sensitive information
safe from cyber attackers.
