This is better than 10 ways to leave your lover?
Few things are more important to the enterprise or for anyone than its data. Data is the GOLD of a company!
Whether its customer information (CRM), intellectual property or capital investment, protecting your assets has become the most critical business process.
Security isn't limited to a single task, but instead requires a layered strategy with ongoing maintenance. So how should the enterprise go about securing their networks from outside attack?
Let's take a look at 10 things you can do to help keep your networks safe:
• Communications – A sound security policy is only as good as the people who must adhere to it. In that regard, it is key to educate your users on how their actions may impact the network.• Virus Management – Viruses and other malware can cause a wide range of problems, from slowing or crippling network activity to theft. So, virus-detection and spyware software must be installed and updated regularly.
• Patch Management – Hackers often use known software security holes to exploit networks. Accordingly, a key component of your defense should involve an automated patch solution.
• Encryption – In the event that your network is compromised, encrypting your data will store it in an unreadable format. This is particularly useful for mobile devices.
• Physical Security – Don't overlook the importance of restricting access to your servers or data center. This can be done with appropriate access control hardware and software.
• Passwords - Dictionary attacks are another tool in the hacker arsenal. Corporate password policy should require strong passwords (a combination of letters, numbers and special characters) and force periodic password changes.
• Vulnerability Scanning – A vulnerability scanning tool will assess any weaknesses within your network and offer suggesting and remedies to help address the issues.
• Spam Filtering – Spam now accounts for a significant portion of corporate email. These messages lure users to click on links intended to pilfer sensitive information. Spam filters can catch these before they land in your users in-boxes.
• Event Logs – Logs are an essential tool in uncovering potential attacks. But volume can quickly make this task unmanageable, so employ the use of log management software to help prevent an attack before it happens.
• Backup and Disaster Recovery – In the event of network failure, you'll want to restore operations as quickly as possible. Backups, with a solid off-site storage strategy can do just that.
Network security can seem like a daunting task. However, today’s environment demands our vigilance. These best practices will help ensure the safety and availability of your networks.
