Now let us know what are the 7 cybersecurity layers and we will discuss each of them. Also, let us know the importance of these cybersecurity layers.
Know About 7 Cybersecurity Layers
This article let us know what are the 7 cyber security layers. But before we discuss that, let us know that the 7 layers of cybersecurity are classified into 3 categories:
1) Prevention
2) Detection
3) Response
So let us know more of these 3 categories from the following:
Prevention:
These layers work to prevent the occurrence of an attack. This includes firewalls, anti-virus software, encryption, and restricting access to networks.
Detection:
These layers provide monitoring and detection of breaches. This includes intrusion detection systems (IDS) and intrusion prevention systems (IPS),.
Also, the log analysis and security information and event management (
SIEM).
Response:
These layers include incident response, identity management, and security governance. It includes the education of employees and users.
Now that we know the three classified categories of seven layers of cybersecurity. Let us know what are those 7 layers of cybersecurity?
1. Access Control Layer
This layer is for the identification and authentication of the following:
- Users
- Systems
- Applications
- Data
It also includes identification management, authorization management, network access control (NAC). Also, the identity-based security policies, identity federation, and access provisioning.
2. Network Security Layer
This layer is for the protection of the network infrastructure itself. It includes the following:
- firewalls
- intrusion detection systems (IDS)
- intrusion prevention systems (IPS)
- anti-virus software
- encryption
- restricting access to networks
This layer aims to prevent an attack from happening in the first place.
3. Data Security Layer
This layer is for the protection of data at rest or in transit. It includes the following:
- Backup
- Encryption
- Patching systems
- Updating systems
- Upgrading systems
- Data storage
This layer aims to prevent data from being stolen or lost by unauthorized individuals. So if an attack occurs through the system.
The main concern here is to ensure that the data cannot be accessed. By anyone other than authorized users who are using authorized devices within authorized locations.
4. Application Security Layer
This layer is for the protection of applications that are used by multiple users over different systems or devices. It includes authentication processes like the following:
- multi-factor authentication
- application hardening
- penetration testing
- code reviews
- vulnerability assessment
Hackers can exploit these vulnerabilities leading to loss of money or confidential information. Which can result in serious repercussions to brand reputation and customer loyalty.
This layer aims to prevent attacks against applications themselves through firewalls. Also, IDS/IPS tools inspect traffic to applications for malicious content.
5. Data Security Layer
This layer is for the protection of data in motion. It includes the following:
- Encryption
- Tokenization
- MFA mechanisms
This layer also provides a level of protection for data that is at rest or in motion. This is accomplished through encryption, tokenization, and multi-factor authentication (MFA).
6. Endpoint Security Layer
This layer is for the protection of systems and devices as well as the users who use those systems. It includes endpoint security software as well as patching operating systems.
Also, applications on those devices are against known vulnerabilities. So they cannot be exploited by the bad guys.
This layer also provides a level of protection for endpoints themselves and the data that is stored on them.
7. Business Continuity Management Layer
This layer focuses mainly on business continuity management (BCM) measures. Which covers both physical business continuity (PBC) measures.
So like business impact analysis (BIA), risk assessments, disaster recovery planning. It is already done and it will be too late to reverse the effects of the attack and prevent any further attacks.
