Defining and assessing the security risks
Define various factors such as the security requirements, how information gets classified, a security policy, how the policy gets monitored and who is responsible for the project. List all the things that are used, interacted with or undergo alterations by the websites. Perform the relevant data classification based on sensitivity and the various ways in which your business gets affected by loss, release or modification of an unauthorised manner. When it comes to deciding the area that will require the maximum protection effort, this classification will come in very handy.
For the very simple systems that do not have any sensitive data, insist on standard security baselines for the development project. For the more complex ones that feature secure data, it is better to have a threat model created that will help in identifying all possible vulnerabilities. This analysis will be of great assistance for the developers in working on your project as per business requirements and allow them to deliver a successful development.
Adopt a holistic view
Information security is more than simply preventing damage or theft of user data. It also involves ensuring that your website is always available, fast enough, complies with the regulatory and legal requirements, provides accurate information and protects users from all unauthorised and inappropriate use. Try to balance the level of security for your website as per the cost constraints and ease of use.
Be it your own data or someone else’s, do not place any trust
Your website will be getting inputs not only from the users but also from various other sources such as purchased data, news feeds, or back-office systems belonging to either your own organisation or your partners. It is important that all of this data undergo appropriate validation at the time of input as well as output so as to ensure protection for the systems as well as users.
Enforced approval and review at every milepost
When you undertake a review of security into the formal approval and milestone of the development project, security features get integrated into the development process all related issues can be tackled as soon as they arise. Earlier you take the security factors into consideration, cheaper it becomes to mitigate all risks in the future. Building a change control methodology into the overall design process is another measure you can take.
Include security at every level of service and contract agreement
Clearly define the sort of security protection you need from your sub-contractors, suppliers, and business partners. When it comes to assessing their security, adopt the same measures as you would do for your own. Identify the security monitoring features required and how to disclose and detect breaches.
