Security as a Service (SECaaS) and Its Categories

Cloud Computing | Security as a Service (SECaaS): In this tutorial, we will learn what is security as a service, its different categories, and its advantages. By Rahul Gupta Last updated : June 03, 2023

What is Security as a Service (SECaaS)?

Increased demand for cloud computing, the advent of intelligent systems, and increased acceptance of bring-your-own-device have all stimulated demand for cloud security services. These consulting and managed services are used to secure and protect cloud computing-related applications, data, and other infrastructure.

The category is dominated by user authentication and identity and access management services, with both a higher market share and a faster growth rate than SIEM (Security Information and Event Management) and other cloud-based security services. The largest vertical for cloud security services have been banking and financial services, while healthcare is experiencing the most significant growth.

Security as a Service (SECaaS) Categories

1. Network Security

Network Security is real-time protection provided either on-site via the installation of software/appliance or through proxying or redirecting web traffic to the service provider through the cloud. On top of items like AV, this provides an added layer of security to prevent malware from entering the enterprise through activities such as web browsing. Government guidelines can also be applied by these network protection technologies about the forms of web access and the times that are appropriate.

2. Security Reviews

Security Reviews are audits of cloud services by third parties or tests of on-site systems based on industry standards. Multiple standards such as NIST, ISO, and CIS are well established and validated by conventional security assessments for networks and applications and compliance audits. There is a relatively mature toolset, and using the SaaS delivery model, a range of tools has been introduced. Subscribers get the usual benefits of this cloud storage variant's elasticity, negligible startup period, low overhead administration, and pay-per-use with low initial investments in the SaaS distribution model.

3. Network Protection

Network Protection consists of security services that delegate access to the underlying resource services, distribute them, track them, and secure them. Architecturally, network security offers services that deal with network security controls in aggregate or directly addressed to each underlying resource's network. Network protection is likely to be supported by virtual devices alongside conventional physical devices in a cloud/virtual world.

4. Encryption Schemes

Usually, encryption schemes consist of algorithms that are computationally difficult or impossible to break, along with encryption and decryption management processes and procedures, hashing, digital signatures, generation and renewal of certificates, and key exchange.

5. Intrusion Management

Intrusion Management is the method of detecting and responding to statistically irregular events by using pattern recognition. This could involve real-time reconfiguration of system components to stop/prevent intrusion. Intrusion detection, prevention and response strategies in physical environments are mature, but the growth of virtualization and massive multi-tenancy introduces new intrusion goals and poses many concerns about the implementation of the same security in cloud environments.

6. Inbound and Outbound E-mail

Inbound and outbound e-mail should be protected by e-mail protection, thereby protecting the company from phishing and malicious attachments, implementing corporate policies such as appropriate usage and spam, and offering options for business continuity. The solution should allow policy-based email encryption as well as integration with different offerings of email servers. Digital signatures that allow identification and non-repudiation are features of several security solutions for cloud e-mail.

Security as a Service (SECaaS) Categories Advantages

The following are the advantages security as a service (SECaaS) categories:

• Develop and manage digital enterprise cloud protection, including microservices, IoT, databases, and apps.
• Build, build, and manage the risk of cloud protection and enforcement guard rails in everyday operations.
• Cloud security workloads such as monitoring, event identification, response and reporting are engineered and coordinated.
• Manage in the cloud the data protection and privacy criteria.
