Building and running your own website can be a daunting task, especially with the cyber crime that you are exposed to. But, says MYRON SALANT of Webafrica, there is no need to panic as there are various services to keep you safe.
The cyber-world can be a dark and daunting place, especially if you are building and running your own websites or have an online business. Cyber-crime in the form of hacking could result in your website being blacklisted by Google, equating to a drop in search rankings, a damaged reputation, and a loss of revenue as you try to get your site back up.
“But there is no need to panic,” says Myron Salant, web services product manager at Webafrica. “Many website owners only think about security after their site gets hacked, but knowledge is power: if you know what the threats are you can arm yourself appropriately and get one step ahead of the hackers.”
Myron has identified the top 10 threats to your website that you should be aware of:
Injection happens when hostile data is sent to an interpreter as part of a query or command. This data tricks the interpreter, resulting in unintended commands and corrupt data. It’s a common problem in web applications, particularly with SQL injection.
When an application sends user-supplied data to a web browser without first validating or encoding it, cross-site scripting (XSS) can occur. This lets hackers execute scripts in the victim’s browser that hijack user sessions or vandalize websites.
Insecure direct object references
Web applications don’t always verify that the user is authorized for the target object. Without an access control check or similar protection, supposedly secure data can be accessed and stolen by attackers.
Cross-site request forgery
CSRF tricks a victim into submitting fake HTTP requests via cross-site scripting or image tags. It’s an issue for web applications that inadvertently allows hackers to predict the details of a transaction – for example, automatically-generated session cookies. Attackers create hostile web pages which generate forged requests indistinguishable from real ones.
Insecure cryptographic storage
It’s hard to believe but many web applications still do not properly protect sensitive data such as credit card numbers and personal details. Attackers can easily access poorly encrypted data and use it to commit credit card fraud, identity theft and other data-related crimes.
Failure to restrict URL access
An application may protect sensitive functionality only by not displaying relevant URLs to unauthorized users. By accessing those ULRs directly, attackers can exploit this weakness to perform unauthorized operations.
Invalidated re-directs & forwards
Web applications may re-direct and forward visitors to other pages and websites without proper validation. Attackers can then re-direct victims to phishing or malware sites or use forwards to access unauthorized pages.
Broken authentication & session management
Account credentials and session tokens are sometimes not properly protected. Attackers simply use stolen passwords, keys and authentication tokens to steal other users’ identities and commit crimes.
Attackers exploit security configuration weaknesses at any level whether it’s the platform, web server, application server, framework or custom code. These flaws give attackers unauthorized access to default accounts, unused pages, un-patched flaws, unprotected files and system data.
Insufficient transport layer protection
When applications fail to authenticate, encrypt and protect sensitive network traffic, they may support weak algorithms, use expired or invalid certificates, or execute commands incorrectly.
“The above threats can simply be avoided by implementing an online security system, such as SiteLock, for example,” says Myron. “If you are unsure about the right security solution for your website, speak to your web developer – as the cliché goes, prevention is better than cure!”
