The types of threats that are most common on front-end or ‘client side’ web applications are e-skimming, formjacking, and cross-site scripting (XSS). Magecart attacks are another common client-side threat targeting organizations.
In terms of the dangers, if an organization becomes the victim of a client-side attack, they may not know it immediately, particularly if they’re not using an automated monitoring and inspection security solution. Sometimes it is an end-user victim (like a customer) that finds out first, when their credit card or PII has been compromised. The impact of these types of client-side attacks can be severe. If the organization has compliance or regulatory concerns, then investigations and significant fines could result.
Other impacts include costs associated with attack remediation, operational delays, system infiltration, and the theft of sensitive credentials or customer data. There are long-term consequences, as well, such as reputation damage and lost customers. If the attack is on a B2B web application, then upstream attacks may also occur on the organization’s clients, depending on the type of data that has been stolen.
Second, sometimes the script found in the third-party library is just poorly written. The code may include tracking or social media tags that get inappropriately installed and end up capturing and sharing sensitive information, like login credentials.
Why is client-side security important and why should businesses prioritize it?
Compliance is also a major concern. Regulatory mandates like GDPR and HIPAA, as well as regulations specific to the financial sector, mean that governments are putting a lot of pressure on organizations to keep sensitive user information safe. Failing to do so can mean investigations and substantial fines.
Right now, a lot of organizations are focused on back-end or ‘server-side’ security. To an extent this is understandable. There’s a lot of news out there about zero days, ransomware, software vulnerabilities, etc., and no one wants to become the latest victim. But ignoring security on the client side is kind of like only insuring half your house—which, of course, no one would ever consider doing. When it comes to business systems, it is incredibly important to secure both the front end and the back end. Businesses need to begin to prioritize the client side.
