Everyday security threats are being modified and refined, as hackers new conduits such as instant messaging, peer-to-peer connections, and wireless networks to deliver their attacks. In my opinion, the biggest headache for small businesses is the misuse of the Internet by employees. If a user visits an inappropriate site, sends or receives inappropriate content, or worse, violates confidentiality and leaks client information or company secrets, legal liability action is sure to follow. End user education needs to be top priority for all network administrators.
Insiders aren’t the most common security problem, but they can be among the most damaging to a company’s reputation. Insider attacks against IT infrastructure are among the security breaches most feared by both government and corporate security professionals. If an employee is terminated, it’s crucial that all system access be revoked immediately. About half of all insider attacks take place between the time an IT employee is dismissed and their user privileges are taken away. I was in a situation where a co-worker was dismissed because of poor work performance. The IT manager arranged for all user privileges to be terminated immediately after the employee was informed of his termination. He was allowed to remove personal items from his office and computer, but was supervised the entire time. There was a tremendous amount of planning involved to coordinate this, but it work effectively. it support orange county
When it comes to current employees, IT managers must keep an eye out for insubordination, anger over perceived mistreatment, or resistance to sharing responsibility or training colleagues, which are all signs someone may be capable of system sabotage or data theft. IT managers must be watchful any time someone with access to sensitive systems has a falling out with his or her bosses.
Second, moderate the effect of spoofed ports and increasing use of port 80 by new services. The most common open port is of course port 80, so attacks directed at a web server will not be stopped by a common firewall. If a needed port is blocked, applications such as instant messaging, and streaming media will automatically use the open port. Trojans can be designed to listen on any port and can be specially designed to look like web traffic. Preventing overuse and misuse can be accomplished by using an application-layer firewall, ensure that a port is open only for specific servers, and configure systems at the host level with port filtering or IPSec blocking policies that can be set to block known troublesome ports. it helpdesk support
Third, everyone agrees that the number one thing that you can do to improve security on a network is to keep patches current. Over ninety percent of systems that have been attacked could have been prevented if known vulnerabilities had been diminished via patches and configuration. Patching plans can be developed and used with enormous benefits. Some ways to mitigate patches are: manually, by downloading the patch, testing and applying it to a system, visiting the Windows Update Site to review the available patches, then deciding to accept or reject any proffered changes. Automatic updates can be configured to periodically connect to Microsoft for inspection and downloading of updates. Software Update Service is a free server application that when configured the system will periodically download patches from Microsoft. Microsoft Systems Management Server with update is purchased separately from Windows operating system and provides multiple management services. And, third-party patching products are available that can provide similar services.
Strengthening authentication processes can also help to secure your network. Authentication can be increased by enforcing a strong password policy. Use some other form of authentication along with this. Use technology and physical security to protect password databases and authentication material. Also you must understand that Windows authentication systems vary, and backward compatibility means less secure authentication may be used even by the most recent version of the operating system. One very important issue is to recognize that your network is only as secure as the least secure part. hipaa compliance network security
Fourth, limit the number of administrators and limiting their privileges can help to secure a network. Don’t automatically give admin rights to the local PC unless there are applications that require it to run needed processes. In most cases administrative rights can be substituted with just elevated or privileged rights. Users with admin rights should be educated about not using that account to read email or surf the Internet. Instead, they should be given an ordinary account for those purposes.
Last, but not least I can’t stress enough the importance of developing and enforcing security policies by ways of accountability, technology and user training. The best knowledge anyone can have on security cannot protect your systems if it not used. Security policies should be enforced by more than technology and fully supported by management People make security work. People support the development of culture of security, and people follow the rules because they understand them and because they are aware of the consequences. Train your users, let them know the rules, and hold them accountable.
