If software is not kept updated across your IT estate, then your security could be at risk. This video identifies the Top 10 most targeted applications and suggests how you can strengthen security and reliability despite the ever-increasing number of vulnerabilities on your network.Looking for some network utilities? There are plenty of options, but don’t waste time on the bulky and more heavyweight contenders, unless you really need them – our Tiny Tools may provide all you need.If you’d like to find out what software is installed across your network, for instance, you could install some expensive commercial solution, complete with database, analytical tools and more. But we’ve found a 160KB program which will scan all your network PCs for no cost at all.And capturing network traffic normally involves installing complex utilities, and a supporting library or two. But if you can get by with raw sockets then the 20KB RawCap will get you started in seconds.This is just the start, though. Other tools in the list will help with performance issues, network management, security, file sharing and more. And they’re all free, and very lightweight: even installing all ten will use less than 7MB hard drive space.


1. Network Stuff 3.0.9 – 1.34 MB

Figuring out what’s happening on your network normally involves a whole library of tools, yet somehow Network Stuff has managed to cram them all into a single portable application.It’s strong on the basics, for instance: the program can display your IP addresses (both local and external), scan your network for other systems, reveal MAC addresses and run graphical ping or traceroutes to the addresses you specify.But Network Stuff can also display all the currently open network and internet connections; use built-in Whois and DNS tools to get more information on IP addresses; remotely wake up or shut down other systems on your network, and the list goes on.The only problem here is complexity, as there’s a lot to explore. If you get lost, though, check the author’s website for some helpful guidance.

2. DNS Jumper 1.0.4 – 812KB
Changing your DNS settings can improve your online security, perhaps give you access to sites you couldn’t reach otherwise, and improve your browsing speed. Windows doesn’t exactly make this easy, but that’s where DNS Jumper comes in.This tiny tool comes with a lengthy list of DNS alternatives. If you’re not sure which is best then it can test them all to find the fastest. When you’re happy, it’s able to apply your preferred DNS settings in a click, and the program can even back up and restore your original settings to avoid the chance of any problems.

3. RawCap 0.1.4.0 – 20KB
Packet sniffing – capturing network traffic for later analysis – can be an invaluable way to diagnose tricky network problems, both hardware and software. And there are few easier ways to get the job done than with the super-lightweight RawCap.The program is a command line tool, but it’s also straightforward to run from Explorer. Just double-click the file, choose your network interface, enter an output file name, and that’s it – the program will capture raw packets and save them in a .pcap file.
Unsurprisingly for a 20KB tool, there’s no help here to analyse the finished results. Just opening the file in Notepad may be enough, though if you’re looking for plain text. And there’s no doubting RawCap’s simplicity: it doesn’t need any other components or DLLs beyond the .NET Framework 2.0.

4. Fast Software Audit 1.0.0 – 160 KB
If you manage a PC network then you’ll know it’s important to keep track of the software your users are installing. You could check this manually, or invest in some big corporate inventory tool, but the ultra-compact Fast Software Audit – portable and only 160KB – could be enough. Just enter the network names of the computers you’d like to audit and it’ll quickly scan them, revealing the list of installed applications. (Though please note, your systems will need the Remote Registry service to be running for this to work.)


5. CloseTheDoor 0.2.1 portable – 484 KB

When you want to secure your network it’s important to understand which processes are listening for connections, and the portable CloseTheDoor will tell you everything you want to know: the network interface, ports, protocols, process, related Windows services and a whole lot more.All this information can seem baffling at first, but CloseTheDoor can help. Right-click something and you’ll find options to search the web for useful information on the process, port and how it’s generally used.And if you do identify malware then CloseTheDoor can even shut down that process, though be careful – if you accidentally terminate something important then you might crash your PC.
