5 Security Issues With Cloud Applications

2011-08-10 - Follow - Comment

http://www.syncing.net/blog_en/2011/08/5-reasons-why-peer-to-peer-software-like-syncing-net-is-more-secure-compared-to-cloud-services-like-google-apps-microsoft-365-and-the-like/

Quick facts:
- The choice: Cloud apps vs. local apps synchronized across PCs
- There are 5 major cloud security issues compared to peer-to-peer sync:
- #1: Centralized data storage on cloud servers is ideal for hackers
- #2: Losing true data authority: Confidential data is open to third parties
- #3: More data transfers needed: Higher probability for interception
- #4: Dependency on health of providers is a loss of control
- #5: Security through redundancy not necessarily by default
- The security solution can be local applications like Micorosft Office plus
synchronization software like SYNCING.NET

Why the password "this is fun" is 10x more secure than "J4fS<2"

2011-08-02 - Follow - Comment

http://vivekgirotra.com/why-the-password-this-is-fun-is-10-times-more

Quick facts:
3 common attacks against passwords executed via automated programs:
- "Brute Force": Try every character combination (256 byte characters)
- "Common Word": Try every common word combination (~1,000 words)
- "Dictionary": Try every dictionary word combination (~500,000 words)
What makes a password more secure:
- Automated programs can try a max amount of combinations per second
- If this amount is not artficially reduced by application delays...
- You have to choose stronger combinations to secure a password
How to choose a more secure password:
- Against "Brute Force": Longer and more complex combinations
- Against "Common Word": More and uncommon words
- Against "Dictionary": More words
Why a password like "this is fun" can be more secure than "J4fS<2":
- There are more words in a dictionary than characters in the alphabet
- You have to Increase the number of combinations to decrease the risk
- This number grows faster with 3 dictionary words than 6 characters
- You don't have to write a dictionary password down to remember

Get rid of Skype style phone numbers

2011-07-28 - Follow - Comment

Just add the following meta tag to your HTML head (uppercase required):
<meta name="SKYPE_TOOLBAR" content="SKYPE_TOOLBAR_PARSER_COMPATIBLE" />

If you want single phone numbers styled as Skype numbers, you have to markup the single phone numbers like this:
<!-- sphoneid telnr="+49 333 88888" fileas="John Doe" -- >+49 333 88888<!-- sphoneid -->

Security issues with browser extensions

2011-07-22 - Follow - Comment

Even Google warns! - Some of my favorite Google Chrome extensions require access to "Your data on all websites" or "All data on your computer and the websites you visit". Technically this means that I grant the developers of such extensions full access to my entire communication with all websites I visit, including login sessions (cookies, password, etc.), private data (docs, e-mails, photos, etc.) even online banking credentials or credit card info - and for some single extensions even worse - to all data on my computers.

Even Google warns not to grant these rights to third parties:

In the future I will only trust extension authorities, which can access my data on their own domains anyway (like Gmail extension for mail.google.com) or install a few necessary extensions only.

[Update] My list for secure and useful Chrome extensions:
