Your network is a prime target for all sorts of enemies, internal and external, that seek to steal your data, disrupt your business operations, or invade your privacy. Fending off such formidable cyber-attackers means identifying network security vulnerabilities and developing fixes.
Only a professional data security and management service like CyberlinkASP can protect your organization and its information from all of the major security vulnerabilities facing your network. To help you navigate the ins and outs of modern network security, we’ve compiled a list of the five most common vulnerabilities.
#1 Weak Passwords
Problem: With all the attention given to password strength, you might think password strength is an issue from a bygone era. Sadly, many organizations still lack robust password protection. Since obtaining a network’s password is still the easiest way to gain access to a system, it remains one of the top security concerns facing businesses.
Fix: Make certain that every account, from a web environment to database servers, is protected by a strong password. Passwords management tools are valuable resources, as are frequent password tests. Default passwords should also be avoided at all costs.
#2 USB Flash Drives
Problem: Internal threats are just as daunting as external threats, if not more so. One of the primary methods of invading or infecting a network is simply to insert a small thumb drive into a computer’s USB port. From hackers armed with targeted malware to spies determined to steal sensitive secrets, a wide range of potential enemies can use thumb drives to gain access to your organization’s networks.
Fix: Automatic encryption of information can prevent malware from infecting a system. Organizations should also develop policies that limit the use of USB drives to certain people and certain computers.
#3 Wireless Access Points
Problem: Unfortunately, wireless access points (WAPs) are often inherently insecure. By turning a legitimate WAP into a rogue access point, hackers can gain immediate entry into a network. In fact, potential attackers can simply roam for unsecured wireless networks and undermine a network’s security architecture.
Fix: Preventing WAP breaches requires 24/7 monitoring of your network. Only by employing security measures such as CyberlinkASP’s round-the-clock data monitoring services can an organization hope to avert such attacks.
#4 Misconfigured Firewalls
Problem: A firewall is one of your biggest assets. When misconfigured, it can also be one of your biggest vulnerabilities. If your organization proceeds on the assumption that its defenses are as strong as medieval fortresses, it better make certain that it is. Unfortunately, many businesses allow misconfigurations of their firewall rulebases to go unnoticed and unfixed for years, a security omission that can lead attackers to gain direct or indirect access to the network.
Fix: Review and update your security policy regularly, ensuring that your firewall rulebase remains relevant to current challenges.
#5 Mobile Devices
Problem: The biggest selling point of smartphones, tablets, and laptops (their mobility), is also their biggest drawback. Bring any infected device into your business environment and it can easily spread the malicious code among your network. Unsecured portable devices are also vulnerable to theft. Unless your data is encrypted, it’s as good as stolen. If it contains cached passwords, emails, sensitive data, and VPN connections, your organization may be in trouble.
Fix: Mandatory data encryption is critical. In particular, you should create an encrypted file system and a policy that forbids sensitive data to be stored on mobile devices.
CyberlinkASP can help you develop a comprehensive security system that identifies and neutralizes not only the most common network security vulnerabilities, but also some of the less common weaknesses.
