Cloud computing:
Cloud computing is the on-demand accessibility of computer system resources such as data storage and computing power without direct active management. In general, it describes the term of the availability of data centres for many users over the internet.
Security as a service:
Security as a service is a business methodology in which a service provider integrates their security services into a corporate infrastructure on a subscription basis more cost-effectively than most individuals or corporations can provide on their own when considering the total cost of ownership.
Security as a service in cloud computing:
Security as a service (SecaaS) is a cloud computing technique that offers managed IT security services over the internet. SecaaS is a software as a service (SaaS) method but bounded to specialized information security services.
Benefits of SecaaS:
Security as a service in cloud computing facilitates organizations in different ways:
- Reduced costs:
SecaaS solutions are provided on a monthly rental basis and per license purchases.
- Ease of management:
A service provider delivers total management of cloud security services, security policies, and general administration. Customizable and scalable services range from anti-virus/malware to outsourced security suite developers.
- Continuous anti-virus updates:
SecaaS services maintain security software with the most current virus definition and security updates.
- Faster provisioning:
The purpose of as-a-service offerings is that you can provide your users access to these tools instantly. Security as a service offers on-demand, so you can scale up and down as you need, and you can do so with speed and cleverness.
- Focuses on important things:
Using a web interface or having access to the management dashboard of your company can make it easier and faster for your security provider to monitor and control security processes within the organization.
- Trained staff for security
When you hire an IT security expert team, it has more skills and knowledge than anybody in your in-house IT team.
- Free up resources
When a third-party is managing your security issues, then your IT team is free, and they can focus on tasks that are essential for your organization.
Responsibilities of SecaaS provider:
- Inter-operable
Have more flexibility by making sure that your service provider has no interoperability issues.
- Low TCO
The total cost of ownership (TCO) is a good criterion for choosing your service provider, which makes sure that you are paying according to your agreement.
- Reporting
Your security service provider should have a reporting mechanism and report your organization on daily and monthly basis that would allow you to see attack logs, major security events, and other essential data in your cloud storage.
