Is the &quot;owner&quot; column the ISP or the owner of the AS (autonomous System<br />
range of the IP range) ? &nbsp;I have a few known ISPs where malicious IP<br />
sources often originate from so this column would be useful.<br />
<br />
Quite a lot of work to do
</div>


<div>
But the nirsoft pages' info was last updated in Apr 2013, rather outdated
</div>


<div>
And for US list, the owner's column is virtually blank

Thanks Dave. Last query: what does RIPE stand for

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.
