Snort: Intrusion Detection/Prevention Management

June 21st, 2007 by Niranjan Kunwar

Snort-1Snort has always been, and still is my favorite IDS (Intrusion Detection System) although I manage many UTM (Unified Threat Management) Firewalls with built in IPS/IDS (Intrusion Detection/Prevention) now. The commercial UTM Firewalls with IPS/IDS are easy to use and configure but they come with a high price tag and aren’t easy to customize. Even though snort is not that easy to install, configure and manage it still is the most popular IDS/IPS today because of the fact that it is open source, free, easily customizable, easy to create rules, signatures are always kept up-to-date by its community and plenty of excellent documentation, guides and books.

Snort captures enormous amount of data from the network and generates alert based on the rules and signatures. There’re currently 3 excellent and relatively user friendly ways to manage and analyze the snort data:

Everything Apple…

June 12th, 2007 by Niranjan Kunwar

Mac OSX Leopard - The latest and greatest Mac OS X, major features unveiled. New Desktop, Finder, Time Machine, Spaces, Quick Look and many more…

Safari for Windows - The sleek and fast apple browser comes to Windows world. I’ve installed it in my windows machine and surfed for a while. The first impression is that, it’s faster than both IE7 and Firefox, but at the same time it’s buggier, in an hour browsing it crashed twice (it’s currently in beta and I’m sure it’ll be fixed soon).

iPhone to Support Third-Party Web 2.0 Applications - So, Apple is allowing the developers to make iPhone apps and host them on their own servers. iPhone is using full Safari-based browser.

WWDC 2007 Keynote (QuickTime Video on Demand) - Watch Apple CEO Steve Jobs unveil and demo Leopard features in his World Wide Developer Conference keynote address from San Francisco’s Moscone West.

ZFS To Become Default File System In Leopard

June 7th, 2007 by Niranjan Kunwar

Macrumors noted, Sun’s CEO Jonathan Schwartz announcing that Apple would be making ZFS the default filesystem in Mac OS 10.5 Leopard. That’s a great news. So, welcome pooled storage and bye-bye volumes!

ZFS stands for Zettabyte File System and was developed by Sun, it offers many advanced features and can handle much more space than the current filesystems used by Windows, OS X or Linux.

ZFS presents a pooled storage model that completely eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted bandwidth and stranded storage. Thousands of filesystems can draw from a common storage pool, each one consuming only as much space as it actually needs. The combined I/O bandwidth of all devices in the pool is available to all filesystems at all times.

All operations are copy-on-write transactions, so the on-disk state is always valid. There is no need to fsck(1M) a ZFS filesystem, ever. Every block is checksummed to prevent silent data corruption, and the data is self-healing in replicated (mirrored or RAID) configurations. If one copy is damaged, ZFS will detect it and use another copy to repair it.

ZFS introduces a new data replication model called RAID-Z. It is similar to RAID-5 but uses variable stripe width to eliminate the RAID-5 write hole (stripe corruption due to loss of power between data and parity updates). All RAID-Z writes are full-stripe writes. There’s no read-modify-write tax, no write hole, and — the best part — no need for NVRAM in hardware. ZFS loves cheap disks.

Your Online Presence Matters

June 1st, 2007 by Niranjan Kunwar

Many smart people have figured out the importance of domain name quite early, and are now multi-millionaires. They came up with many different (smart and weird) business models with the domain name. Check this fascinating story about The man who owns the Internet. Ok that was for business, but how about the domain name for individuals? There’s no doubt that now it’s becoming critical for individuals too. A recent study showed that one in five employer searches the information about the cantidate in internet and 59 percent of those said it influences recruitment decisions. Fortunately you can have your say in what Google says about you. So, individual’s online presence is more important than ever before.

I remember having a hard time finding an appropriate domain name for this site when I started blogging. Today, I decided to check if there were any leftover domain names for me to nab. All the .com, .net and .org domains with my name were already taken. So, I tried my family name, and was lucky to find kunwar.org free. I’ve registered it and forwarded the domains niranjan.kunwar.org and kunwar.org to this site. Maybe in the future I can provide a sub-domain to each and every member of my family :) . Also found niranjankunwar.com free, and nabbed that too.

If you’re lucky enough to still get a domain with your first name or family name you should just grab it. I register my domains at Netfirms, it’s pretty cheap — $4.95 for first year and $9.95 per year thereafter.

What do you think about online presence and owning your own domain name?
