Interesting tidbits of information:

E-mails, contracts, and PowerPoint files account for 80 percent of corporate information.

71% Use Email to Negotiate Contracts and Agreements

69% Use Email to Exchange Invoices, Statements, and Payment Information

93% Use Email to Communicate with Customers.

38% Use Email to Respond to Regulators

44% Use Email to File with Official Bodies

35% Use Separate Back-End System for Email Retention

23% Use Records Management System for Managing Email

34% Use Document Management System for Managing Email

40% Use Email Management and Archiving Software

There are currently over 10,000 U.S. federal, state, and local laws and regulations addressing what, how, when and why records must be created, stored, accessed, maintained, and retained over increasingly longer periods of time.

The Education sector accounted for the majority of data breaches with 30%, followed by Government (26%) and Healthcare (15%) – almost half of breaches (46%) were due to theft or loss with hacking only accounting for 16%.

Hacking resulted in 73% of identities being exposed

1:400 emails contain confidential information
1:50 network files are wrongly exposed
Breaches on the rise
2005:107 companies exposed 56M individual data records
2006: In 6 months, 40 companies and government agencies have exposed nearly 30M individual data records

IT Professionals need to address mission-critical administration concerns with in-depth, concise coverage. Some sample topics would be:

Defending the company’s sensitive information against security problems

Neutralizing the threat of computer viruses

Identifying potentially disastrous hardware conflicts

Unlocking the hidden usefulness of Windows NT utilities

Creating seamless Windows NT and Unix interoperability

Integrating emerging Internet technologies with your network

Application Security Testing Concerns / Advice

Posted in Application,Security (1500),Web Services (250) by Guest on the March 17th, 2009

Cross Site Scripting
Cross-site scripting allows hackers to:
1)      Execute malicious script in a client’s Web browser
2)      Embed <script>, <object>, <applet>, and <embed> tags
3)      Steal web session information
4)      Modify user’s screen
a.       Any Dynamic HTML code based on content that users submit is vulnerable 

SQL Injection
1)      Users control the criteria of SQL statements
2)      Hackers enter values that alter the original intention of the SQL statement
3)      Four common examples of SQL injection:
b.      Probing databases
c.       Bypassing authorization
d.      Executing multiple SQL statements
e.       Calling built-in stored procedures 

Cryptographic Hacking
1)      Hacker only needs
2)      3 of 4 cryptography components
3)      Text + CipherText + Algo > Deduce the key
4)      CipherText + Algo + Key > Deduce the Text
a.       Algorithms … Do not remain a secret for long
b.      Key … As strong as technique used to create it 

COM Safe for Script Issues
1)      Is your control really Safe
2)      COM controls can be repurposed
3)      Warnings are optional 

Best Practice Medicine:
1)      Implement Security as a Design Feature
2)      Do Not Store un-encrypted Secret Information
a.       Use Crypto
3)      Sign your controls with digital signatures
4)      Consider binding the control to your site
5)      Use managed code 

Denial of Service Attacks
1)      Application or operating system failure
2)      CPU starvation
3)      Memory starvation
4)      Resource starvation
5)      Network starvation  

Best Practice Medicine:
1)      Security as a Design Feature
2)      Do Not Trust User Input
3)      Fail Intelligently
4)      Test Security 

Application Blocks
1)      Caching App. Block
2)      Offline App. Block 

Cache
1)      Instead of roundtrip to server
2)      Read-only reference data
3)      Data destined for remote
4)      servers while consolidating 

Caution
1)      Avoid volatile cached data
2)      Avoid sensitive cached data 

General
1)      Rely on System Garbage Collectors (resourcing)
2)      Avoid custom GC logic 

Use background thread for
1)      Lengthy initialization
2)      Remote service calls
3)      I/O Processing 

Foreground Thread
1)      Default when using Thread()
2)      Prevent process from terminating
3)      Background Thread
4)      Thread.IsBackground()

Are you the next target

They’re after you, who are they?

  1. Competitors
  2. Disgruntled employees
  3. Upset customers
  4. Hackers out for a lark
  5.  Hactivists
  6. Cartels that can buy the latest gadgets and best brainpower
  7. Hostile foreign governments / nations

Your organization may not be a specific target, just on that had a few vulnerabilities as it was probed. Make you not want to sleep at night if you’re worried about protected your networks.
 

Remain ever vigilant. For-warned is forearmed
Unlimited and constant Internet connection for all employees invites trouble. New Malicious code is

Unlimited and constant Internet connection for all employees invites trouble. New Malicious code is introduced daily into the Internet. This constant connection, give intruders more time to find vulnerabilities and gain access.

  1. Hire subject matter experts
  2. Buy business continuity insurance
  3. Reassign and train internal personnel
  4. Contract for specific services, retraining central IT to control specialized resources internally

Information Operations; When used in concert, their sum is far more powerful than the individual components, creating a powerful (deterrent) means towards attaining and maintaining a competitive advantage.

Securing the confidentiality of PHI

PHI (Protected Health Information) requires passwords but….

a) Easy-to-guess passwords are one of the top ten threats to network security

b) When passwords change often to improve security, users write them down, increasing the risk of a breach

In addition, employers must block terminated staff from continued access to systems that have PHI.

However, it is difficult to revoke access to multiple systems quickly.

“Centralized Password Management”. Centralized Password Management lets organizations easily enforce an unlimited number of strong password rules, such as minimums on length, unique characters, letters and numbers required, etc, to maintain security.

Centralized password management allows for, strong, complex password enforcement in addition it allows for:

  1. Password synchronization 
  2. Integration of multiple passwords 
  3. Simplified password resets 
  4. Correction of forgotten passwords
  5. Password administrative revocation
  6. Password change privileges instantly and automatically on multiple systems
  7. Saving administrative Time and $Money
  8. Increases Corporate and Stockholder value

From DOS, Windows, Windows 9x / XP Windows NT, and OS/2

You can use the following procedure to identify your video card.

From a command prompt type the “debug” command and hit enter. You will leave the C:> prompt and be put in the debug’s “-” dash prompt.

C:> DEBUG

At the dash prompt type “d C000:0010” and hit enter.

C:>debug

-d  C000:0010

You will be given some out put in text in to the far right hand side of the output. In this text output you will see the name, though possibly broken up, of your video card.

Here is an example of the debug procedure done on a 9FX Motion 771 with the S3-968 chipset and the 2.05.15 bios revision:

By hitting “d” and enter again at the dash prompt you will see a continuation of the above output which will identify the chipset (in this case 968) and bios version (shown here as 2.05.15).

C:>

By hitting the “q” key ( for quit ) and then enter, you will exit the debug session and return to the “C:>” command prompt.

Note: From Windows 3.1x or Windows 95 you can also do the following:

Check STATUS in HawkEye control panel. Click on STATUS, make note of information listed for Product Name, and Processor Type.

Compare the information gathered from either HawkEye or DEBUG to the chart below, this will indicate which Number Nine Product is installed in the system.
