Virtual Private Networks (VPN) the Insecure Solution
Many organisations have deployed VPN’s as a quick win solution and have suffered as a result of not implementing a full solution. Trinity Security Services’ Consultants have worked with a wide array of customers to solve security issues as a result of hastily rolled out VPN solutions.

A White Hat's Penetration Test
This tutorial is more of a “case study”, in which I describe a recent penetration test I performed. Due to the success of the penetration test (in a relatively very short time) I decided to share this experience with you.

Securing
Network Resources
Network
attacks are the biggest risk for Windows 2000 servers. Since
the release of the old Windows NT 3.1, hackers have been actively
looking for bugs in Microsoft Windows operating systems. Tools
like SecHole, IISInjector, NAT (NetBIOS Auditing Tool), SMBRelay
and L0pthcrack have been developed to reveal passwords, execute
actions on a server, forge network connections and degrade system
performance. In addition, several critical security vulnerabilities
have been recently released for Windows 2000 that can completely
expose a network to an intruder.

Economic
Report: The ROI of Network Integrity
It
has become more difficult to control network security investments,
including escalating labor costs that are growing at the rate
of 31.7% annually. Combine these investments with the surge
in personnel time allocated to security tasks versus network
provisioning responsibilities - at a steep ratio of 3:1 - and
the result is clear: businesses are losing the battle to balance
security with network availability.

The
Database Security Checklist
Database
security can jeopardize your network security. The security
administration of your RDBMS (Relational Database Management
System), needs to be focused on preventing the unauthorized
use of your company or business information by criminals.

The
Principles of RDBMSs Security
Databases
are a goldmine for criminals. Successfully tracking an intrusion
can depend 100% on administering database accesses and permissions.
Unauthorized user actions, as well as possible intruder actions,
need to be tracked and audited in order to maintain the integrity
of the information stored in the database. http://www.securitypronews.com/2003/1118.html

One area that I spend a bit of time on is the Summary Statistics

Restricting
Access by Time of Day
Problem
You want a service to be available only at certain times of
day.
Solution
For xinetd, use its access_times attribute. For example, to
make telnetd accessible from 8:00 a.m. until 5:00 p.m. (17:00)
each day: http://www.securitypronews.com/2003/1016.html

Encrypting
Backups
| Method
1 produces a backup that may be considered fragile: one big
encrypted file. If part of the backup gets corrupted, you might
be unable to decrypt any of it.
Method 2 avoids this problem. The cp -l option creates hard
links, which can only be used within a single filesystem.

OS
Fingerprinting with ICMP
Operating
System (OS) fingerprinting is the process of learning what operating
system is running on a device. This can be used by the curious
network administrator when they see a new device on the network.
Most likely, however, OS fingerprinting is done by an unwarranted
party on your network.

to test connectivity between devices.

Securing A Wireless Network
Most people know that your wireless/cordless phone is, by itself, pretty insecure. A phone of the same model or a receiver set to the right frequency can easily pick up the transmission – utilizing your phone or listening to your conversation. Luckily, the limited range of these devices and the sheer numbers of them are good limiting factors to this type of privacy breech. Still, a phone with a cord connected to the wall is much more secure than a phone with an antenna.

3 Tips For Securing Your Windows Network Properly
One of the wonderful things about Windows 2000 and Windows server 2003 is that you can delegate administrative tasks in your domains. You no longer have to give full administrative privileges to help desk employees, for example, when you just want them to be able to reset passwords.

Security
Trends
You set
up firewalls, e-mail filtering, Intrusion Detection Systems (IDS), personal firewalls,
Censor Software (both on network and personal level) and they still get in. What
I'm referring to are those pesky VBSes, similar worms inhibiting the Windows platform
right now and maybe a few real life crackers here and there. For the network administrator,
this can be a real problem. Even when he has secured his network with the latest
tools and patches, there is still a big chance of his kingdom getting infected,
especially if it's made up of MS Windows machines, and its trusting users.

IDS-Can
You Afford Not To Have One?
Everyone
has an opinion as to the longevity of this type of technology, its validity and
its capabilities as a security tool. Most security professionals will agree that
an IDS cannot be used as your only form of defence. If an IDS is deployed in the
correct manner, that is as part of an overall security program, with the correct
processes and procedures in place governing operation maintenance and incident
handling, can an organisation afford to be without one?

Your Web Server For Enhanced Security
Masking or anonymizing a Web server involves removing identifying details that intruders could use to detect your OS and Web server vendor and version. This information, while providing little or no utility to legitimate users, is often the starting place for crackers, blackhat hackers and "script kiddies".
