How to use Video chat on Facebook

  1. Just go to http://www.facebook.com/videocalling
  2. Get Started
  3. See this. You will need to download and install something on your computer.And calls are just one on one (Unlike Google Huddle which can have upto ten people and also doesnot need any installer -esp if you use Chrome)
  4. Send a video message if your friend is not available. (that beats Google Huddle which doesnot seem to have the video inbox feature yet)

 

CloudNumbers.com – #Rstats gets real in the cloud

I came across Cloudnumbers.com . Awesome name , I didnt know groovy domain names existed anymore.

What is cloudnumbers.com – The website which looks like the salesforce.com website in style and design-

says-

Things are still very raw here- but its an awesome concept. With 68 GB of Memory, I am sure R can blow away everything out of the water.

Probably the competition needs to ahem launch that private cloud soon, before they lose the momentum.

and you Get 2GB of storage, 2GB of traffic and 10h computation cost per month for free! I think this German startup has hit the nail on the head and it would be interesting to see what the future holds.

Happy Fourth of July

 

Thank you America-

for creating in no particular order of importance or chrnology

The Internet , The Atom Bomb and Men on the Moon

Hollywood Movies and Cartoons and Comics and Bbq Burgers,

Chewing gum and Rock and Roll and Stand up Comedy,

Basketball and American Football, and Sports Marketing

but on the whole, just have a good time.

 

Cyber Attacks-Protecting your assets and people from cyber attacks

Cyber Attacks-Protecting your assets and people from cyber attacks

Everyday we hear of new cyber attacks on organizations and countries. The latest attacks were on IMF and 200,000 accounts of Citibank and now the website of the US Senate. If some of the most powerful and technologically advanced organizations could not survive targeted attacks, how effective is your organization in handling cyber security. Sony Playstation, Google Gmail, PBS website are other famous targets that have been victimized.

Before we play the blame game by pointing to China for sponsoring hacker attacks, or Russian spammers for creating Bot Nets or ex Silicon Valley /American technology experts rendered jobless by off-shoring, we need to both understand which companies are most vulnerable, which processes need to be fine tuned and what is the plan of action in case your cyber security is breached.

Which companies are most vulnerable?

If you have valuable data, confidential in nature , in electronic form AND connectivity to internet, you have an opening. Think of data as water, if you have a small leakage all the water can be leaked away. To add to complexity, the attackers are mostly unknown, and extremely difficult to catch, and can take a big chunk of your credibility and intellectual property in a very short time.

The best people in technology are not the ones attending meetings in nicely pressed suits– and your IT guy is rarely a match for the talent that is now available on freelance hire for cyber corporate espionage.

Any company or organization that has not undergone through one real time simulated cyber attack or IT audit that focuses on data security is very vulnerable.

Which organizational processes need to be fine tuned ?
Clearly employee access even at senior management needs to be ensured for both technological as well as social vulnerability. Does your reception take the name of senior management if cold called. Do your senior managers surf the internet and use a simple password on the same computer and laptop. Do you have disaster management and redundancy plans.
A wall is only as strong as its weakest brick and the same is true of organizational readiness for cyber attacks.

What is the plan of action in case your cyber security is breached?
Lean back, close your eyes and think your website has just been breached, someone has just stolen confidential emails from your corporate email server, and complete client as well as the most confidential data in your organization has been lost.

Do you have a plan for what to do next? Or are you waiting for an actual cyber event to occur to make that plan.

Top 25 Errors in Programming that lead to hacker attacks

I am elaborating an earlier article on https://decisionstats.com/top-25-most-dangerous-software-errors/ based on my continued research into cyber conflict and strategy. My inputs are in italics – the rest is a condensed article for further thought.

This is thus a very useful initiative for the world to follow and upgrade their cyber security.

It is in accordance with the US policy to secure its cyber infrastructure (http://www.whitehouse.gov/the-press-office/remarks-president-securing-our-nations-cyber-infrastructure)  and countries like India, and even Europe as well as other nations could do well to atleast benchmark their own security practices in software and digital infrastructure with it. There seems to much better technical coordination between rogue hackers than patriotic hackers imho 😉


The Department of Homeland Security of the United States of America has just launched a list of top 25 errors in programming or creating software that increase vulnerability to hacking attacks. The list which is available at http://cwe.mitre.org/top25/index.html lists down a methodology fo measuring vulnerability called Common Weakness Scoring System (CWSS) and uses that score to rank the various errors as well as suggestions to eliminate these weaknesses or errors.
Measuring Weaknesses

The importance of a weakness (that arises due to software bugs) may vary depending on business usage or project implementation, the technologies , operating systems and computing environments in use, and the risk or threat perception.The Common Weakness Scoring System (CWSS) provides a mechanism for scoring weaknesses. and provides a framework for prioritizing security errors (“weaknesses”) that are discovered in software applications.
Identifying Weaknesses
For example the number 1 weakness is shown with
1CWE-89: Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’).
The rest of the weaknesses are

RANK SCORE ID NAME
[1] 93.8 CWE-89 Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’)
[2] 83.3 CWE-78 Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’)
[3] 79.0 CWE-120 Buffer Copy without Checking Size of Input (‘Classic Buffer Overflow’)
[4] 77.7 CWE-79 Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’)
[5] 76.9 CWE-306 Missing Authentication for Critical Function
[6] 76.8 CWE-862 Missing Authorization
[7] 75.0 CWE-798 Use of Hard-coded Credentials
[8] 75.0 CWE-311 Missing Encryption of Sensitive Data
[9] 74.0 CWE-434 Unrestricted Upload of File with Dangerous Type
[10] 73.8 CWE-807 Reliance on Untrusted Inputs in a Security Decision
[11] 73.1 CWE-250 Execution with Unnecessary Privileges
[12] 70.1 CWE-352 Cross-Site Request Forgery (CSRF)
[13] 69.3 CWE-22 Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’)
[14] 68.5 CWE-494 Download of Code Without Integrity Check
[15] 67.8 CWE-863 Incorrect Authorization
[16] 66.0 CWE-829 Inclusion of Functionality from Untrusted Control Sphere
[17] 65.5 CWE-732 Incorrect Permission Assignment for Critical Resource
[18] 64.6 CWE-676 Use of Potentially Dangerous Function
[19] 64.1 CWE-327 Use of a Broken or Risky Cryptographic Algorithm
[20] 62.4 CWE-131 Incorrect Calculation of Buffer Size
[21] 61.5 CWE-307 Improper Restriction of Excessive Authentication Attempts
[22] 61.1 CWE-601 URL Redirection to Untrusted Site (‘Open Redirect’)
[23] 61.0 CWE-134 Uncontrolled Format String
[24] 60.3 CWE-190 Integer Overflow or Wraparound
[25] 59.9 CWE-759 Use of a One-Way Hash without a Salt
Details of each weakness is given by http://cwe.mitre.org/top25/index.html#Details
It includes Summary , Weakness Prevalence, Consequences, Remediation Cost, Ease of Detection ,Attacker Awareness and Attack Frequency .In addition the following sections describe each software vulnerability in detail- Technical Details ,Code Examples ,Detection Methods ,References,Prevention and Mitigation, Related CWEs and Related Attack Patterns.
Other important software weaknesses are –

[26] CWE-770: Allocation of Resources Without Limits or Throttling
[27] CWE-129: Improper Validation of Array Index
[28] CWE-754: Improper Check for Unusual or Exceptional Conditions
[29] CWE-805: Buffer Access with Incorrect Length Value
[30] CWE-838: Inappropriate Encoding for Output Context
[31] CWE-330: Use of Insufficiently Random Values
[32] CWE-822: Untrusted Pointer Dereference
[33] CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization (‘Race Condition’)
[34] CWE-212: Improper Cross-boundary Removal of Sensitive Data
[35] CWE-681: Incorrect Conversion between Numeric Types
[36] CWE-476: NULL Pointer Dereference
[37] CWE-841: Improper Enforcement of Behavioral Workflow
[38] CWE-772: Missing Release of Resource after Effective Lifetime
[39] CWE-209: Information Exposure Through an Error Message
[40] CWE-825: Expired Pointer Dereference
[41] CWE-456: Missing Initialization
Mitigating Weaknesses
Here is an example of the new matrix for migrations that also list the top 25 errors . This thus shows a way to fix the weaknesses and relative impact on each weakness by the following mitigations.
http://cwe.mitre.org/top25/mitigations.html#MitigationMatrix

Effectiveness ratings include:

  • High: The mitigation has well-known, well-understood strengths and limitations; there is good coverage with respect to variations of the weakness.
  • Moderate: The mitigation will prevent the weakness in multiple forms, but it does not have complete coverage of the weakness.
  • Limited: The mitigation may be useful in limited circumstances, only be applicable to a subset of this weakness type, require extensive training/customization, or give limited visibility.
  • Defense in Depth (DiD): The mitigation may not necessarily prevent the weakness, but it may help to minimize the potential impact when an attacker exploits the weakness.

Within the matrix, the following mitigations are identified:

 

  • M1: Establish and maintain control over all of your inputs.
  • M2: Establish and maintain control over all of your outputs.
  • M3: Lock down your environment.
  • M4: Assume that external components can be subverted, and your code can be read by anyone.
  • M5: Use industry-accepted security features instead of inventing your own.

The following general practices are omitted from the matrix:

  • GP1: Use libraries and frameworks that make it easier to avoid introducing weaknesses.
  • GP2: Integrate security into the entire software development lifecycle.
  • GP3: Use a broad mix of methods to comprehensively find and prevent weaknesses.
  • GP4: Allow locked-down clients to interact with your software.
