When it comes to anything that exists in the digital realm, one of the top questions that come to everyone’s mind is ‘How secure is it?’ The convenience of technology, as well as its many gifts to mankind, is undeniable, but it is, without fail, accompanied by an abundance of concern about security and rightly so. Allow us to explain — most entities in this regard collect crucial and vital details about users, often including sensitive data about their bank accounts, and more if this data was to fall in the hands of infamous elements; there’s just no telling the kind of damage they’d be able to inflict.
Of course, this stands true for all apps, websites, and more,no matter the platform or programming language used to create them. However, in this article, we’ll restrict the scope of the discussion to Angular apps and how one can ensure the highest levels of security while putting together apps with this platform. It is not to say that Angular isn’t an excellent tool for developing robust apps or that it lacks in any way, especially in the context of security. This article is merely a collection of some compelling tips and best practices that can help developers safeguard their Angular app to ensure that their product can continue to deliver optimal performance without being bogged down by security-related issues.
Fend off cross-site scripting: Cross-site scripting attacks, or simply XSS, is when hackers or other entities with malicious intent can inject client-side scripts or other mischievous code into web pages that are visited by users. In this context, Angular uses two methods, sanitize and bypassSecurityTrustX, to deal with untrusted values. So, in the event you need to deactivate this sanitization, make sure that you have thought the decision through and practice ample caution while doing so, for even one vulnerability could inflict severe damage.
Please make use of content security policy: Yet another handy tool one mustn’t forget to use of the Content Security Policy (CSP), which is a supplementary film of security that assists the endeavor in thwarting attacks that aim to damage the website, steal data, distribute malware, and more. CSP helps with both, identifying as well as preventing specific offenses, including data injection and cross-site scripting attacks among others.
Safeguard against cross-site request forgery (XSRF): Also referred to as session riding and one-click attack, XSRF is the type of attack when a user’s trusted web app is used to send unaccredited commands. Prevent such attacks by using the following method: the app server sends an arbitrary verification token through a cookie. The receiving code then reads the cookie and adds a tailored request header in all following request tokens. Finally, the server compares the received cookie’s value against the requested header value and dismisses the request if something is found to be amiss.
Be it an AngularJS application development project you are working on or one involving any other resource; security should never be ignored or underestimated. Also, with tips such as the ones listed above, securing your Angular app is pretty simple.
