Web security is the process of securing confidential data stored online from unauthorized access and modification.
Most businesses are aware that a spam filter and antivirus program are not all they need to protect themselves from the constantly evolving landscape of cyber security threats. Knowing just what a comprehensive security stance entails, however, is far less obvious.
Comprehensive web security includes a full suite of tools to protect against malware infections, data breaches, and service disruptions. It protects the server, network, and email system. It includes advanced technologies like a web application firewall and involves proactive steps like vulnerability scanning.
Web security encounter lots of challenges. And you will read about the most common ones as you read on.
Preventing damage from insider attacks is largely about limiting the amount of access a malicious insider has. This means setting logical access control policies to implement the principle of least privilege. And also monitoring the network with audit and transaction logs. A solution like Liquid Web’s custom Malicious Activity Detector (MAD) will also guard against threats. Both from within and outside the organization.
Most businesses are aware on some level of the security threat posed by malware. However, many people are unaware that email spam is still the main vector of malware attack. A robust email scanning and filtering system is necessary, as are malware and vulnerability scans.
Any device or system infected with malware must be thoroughly scrubbed. Which means identifying the hidden portions of code and deleting all infected files before they replicate. This is practically impossible by hand, so requires an effective automated tool.
Hackers are sometimes able to exploit vulnerabilities in applications to insert malicious code. Other kinds of code injection attacks include SQL injection, shell injection, operating system command attacks, script injection, and dynamic evaluation attacks.
Distributed Denial of Service Attack
A Distributed Denial of Service (DDoS) attack generally involves a group of computers, harnessed together by a hacker. This is to flood the target with traffic.
Put your disaster recovery plan into effect if your company is a victim of DDoS attacks. And at the same time communicate with employees and customers about the disruption. Use a security tool to close off the port or protocol affected by the attack. An example of this tool is WAF. Hence in a process which will likely have to be repeated as attackers adjust their tactics.
Service will best be restored with a content distribution network (CDN). For instance, CloudFlare. Which can absorb an enormous impact while identifying and then filtering out malicious traffic. Make sure to also look for DDoS protection with real-time monitoring for comprehensive mitigation of attacks.
The range of common causes of breach in data include software misconfiguration, lost hardware, or malware.
Data breach prevention requires a range of good practices. Encrypting site traffic and also transactions with SSL is important. Also practice good password hygiene. The principle of least privilege is worth noting here, as well.
To Wind Up
Whether it is causing site damage or defacement, stealing sensitive information or initiating a DDoS attack, the scope to suffer a cyber-attack has increased substantially with websites the first to be exploited. Hence companies must ensure to have tight web security measures to avoid facing issues which can affect the company.
