You can prevent these ports from being exploited by simply running a firewall such as Zone Alarm (<a href="http://www.zonelabs.com/store/content/catalog/products/sku_list_za.jsp" rel="ugc">http://www.zonelabs.com/store/content/catalog/products/sku_list_za.jsp</a>). &nbsp;They will block any TCP port 135/139 traffic. &nbsp;

I disabled file & printer sharing, but the ports remain open.

<div class="content wysiwyg-content">
According to nmap, the following ports are open on my computer:<br />
<br />
135/tcp &nbsp;open &nbsp; &nbsp; msrpc<br />
139/tcp &nbsp;open &nbsp; &nbsp; netbios-ssn<br />
<br />
<br />
My understanding is the msrpc is the server that formerly was vulnerable to the msblast worm, so I'd like to disable it. I probalby don't need it open, right? How can this be done?<br />
<br />
Also, is there a reason not to disable the netbios-ssn process? If so, how can I stop the process from running?<br />
<br />
Thanks.

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.
