Cybersecurity dangers to enterprises grow year after year. Companies, however, can tackle new threats by using an integrated approach to cybersecurity.
A layered cybersecurity strategy is one that employs numerous technologies and protocols to establish protections across the network. Each of these seven levels works in combination with the others to deliver comprehensive environmental protection.
A thorough plan like this ensures that each component of the network is protected and actively maintained to deter all forms of threats.
What Components Comprise a Layered Security Programme?
1. Perimeter Security: Data traveling via a network’s outer edge, or the wall dividing an internal network and an external network, is protected by perimeter security solutions. It serves as a safeguard for the company.
There are numerous technologies available to accomplish this, including unified threat management (UTM) and firewalls for web applications.
UTM is a comprehensive solution that combines technology such as next-generation antivirus, firewalls — which defend the overall network’s security — intrusion detection, spam, and content filtration, and even VPN — a secured online connection that connects your devices and networks.
While perimeter security prevents dangers from entering a network, additional layers of defence detect any risks that are active within it.
2. Network Security Monitoring: Network monitoring solutions enable a company to evaluate activities throughout the system and have complete visibility in order to detect suspicious activity.
This layer includes tools such as security information and event management (SIEM) and network detection and response (NDR).
SIEM is a surveillance and event management solution that may notify stakeholders about any unusual login attempts. These notifications can also be forwarded to an IT staff for prompt action.
Network detection and response (NDR) is identical, except it focuses on detecting unusual activities in network traffic.
Aside from these tools, an organisation’s workers serve as a security layer.
3. Security Awareness: Security awareness may appear simple, yet it is one of the most potent tools a company can use in a multi-layered plan. Given that human error is the top cause of data breaches along with other successful cyberattacks, companies should engage in cybersecurity training to ensure that their employees are equipped to detect and report threats.
In an era when social engineering assaults are frequent, a cybersecurity awareness campaign is a good method to protect a business. A programme like this educates staff on cybersecurity best practises, password hygiene, phishing awareness, and other topics.
4. Endpoint Protection: The Internet of Things (IoT) – an interconnected system of computing and electronic gadgets — keeps organisations connected, but it also creates a broad attack surface. Endpoint protection can be used to safeguard this surface.
Endpoints are ubiquitous in today’s business setting: smart televisions, mobile phones, printers, vending machines, and so on. DNS and managed detection and response (MDR) protection can help safeguard these endpoints.
DNS protection prevents devices from visiting dangerous websites, while MDR protection monitors each device’s operations to detect irregularities and respond quickly.
Furthermore, using advanced technology that captures behavior connected with assaults that sneak through gaps and then stay in the system for a long amount of time only gathering information, persistence detection stops fraudsters from entering your network.
These solutions are useful for firms with a remote workforce since threats can enter inadvertently via an unsecured network connection or a rogue website.
5. Information Security: This layer safeguards data availability, confidentiality, and integrity. It enables a company to protect its own and customers’ private data.
Data loss prevention (DLP) is a component of this layer that prevents illegal information transfer from within the company to the outside. DLP creates rules for securely storing and accessing data.
Furthermore, an email protection system aids in the prevention of common risks like as phishing attempts, spam, and viruses that are spread to end users via email servers.
6. Authentication Protocols: Authentication solutions, as the name implies, verify that the persons accessing an organisation’s business information are who they claim to be.
Authentication is a simple and extremely effective method of preventing unauthorised users from entering your network or obtaining your data.
Businesses should implement MFA (multi-factor authentication), a system that asks users to validate their identity using an additional way of confirmation, such as an app, biometric scan, or code transmitted to a device.
An automated password management system is another utility at this layer. This technology can automatically remind users to update their passwords, preserve a complete record of password history, and encrypt all data collected.
7. Critical Asset Security: Businesses should also be ready if an assault or breach is successful. In the end, no matter how strong the security, the chance of a fresh exploit sliding through the holes exists, and every organisation must have a plan in place to deal with it.
Backup and disaster recovery (BDR) services guarantee that an organisation’s critical data is safely stored, whether on local servers or on the cloud.
This layer includes software-as-a-service backup, which secures data saved in customers’ cloud apps, and website backup, which recovers data online in the event of a breach.
All of these layers combine to form a complete and effective cybersecurity plan that protects every aspect of a company’s network. Security leaders should examine theirs and patch any susceptible levels so that the company can continue to operate normally.
