ISATAG: neznam, ale da se to udelat tak, ze napises text a pak jej screenshotnes a pastnes.... ale takovahle vec asi ne-uplne zajisti nejakou bezpecnost... proc nechces pouzivat PGP? Co je cilem, pred kym ty emaily chranis?

Mam dotaz. Existuje nejaky emailovy klient (idealne addon do thunderbirdu), ktery by mi cely napsany text jednoduchym kliknutim prevedl do jpeg nebo neceho podobneho v tele emailu?
Tj. aby se emaily ode me nedaly dale zpracovavat copy-pastem, menit a updavovat v odpovedi apod. Porebuju neco, kde cilovy clovek nepouziva PGP nebo neco podobneho.

Takovej pop clanek ... ale patri k tematu

OVERDRIVE: Snort, já používal distribuci snorby

A byl jsem na přednášce od Invea-tech a jejich flow-mon, zajímavý, ale ne free pochopitelně.

QWWERTY: Muzes mit vic verzi, zkusil bych dogooglit jak je prepinat na zaklade appky, pripadne bysem asi virtualizoval a hodne ladil firewall

A new freeware version of Netwitness' core product, NetWitness Investigator, was made available today. I was able to get access to it several days ago for a test run. It looks and feels much like Wireshark, but with a lot more capability. The only two issues I found with the tool is that the registration process (required) is a bit quirky but eventually works, and you'll see a noticible drop in computer performance while its running. But considering that this is a sniffer on steroids I suspect that a performance drop is to be expected.

Here are notes from the NetWitness web site:

Product Features:

Captures raw packets live from most wired or wireless interfaces
Imports packets from any open-source, home-grown and commercial packet capture system (e.g. .pcap file import)
License supports 25 simultaneous 1GB captures - far exceeding data manipulation capabilities of packet tools like Wireshark
Real-time, patented layer 7 analytics
– Effectively analyze data starting from application layer entities like users, email, address, files , and actions.
– Infinite, free-form analysis paths
– Content starting points
– Patented port agnostic service identification
Extensive network and application layer filtering (e.g. MAC, IP, User, Keywords, Etc.)
IPv6 support
Full content search, with Regex support
Exports data in .pcap format
Bookmarking & history tracking
Integrated GeoIP for resolving IP addresses to city/county, supporting Google® Earth visualization
NEW! SSL Decryption (with server certificate)
NEW! Interactive time charts, and summary view
NEW! Interactive packet view and decode
NEW! Hash PCAP on Export
NEW! Enhanced content views

msm1267 writes: Two Belgian security researchers from the University of Leuven have driven new nails into the coffin of the RC4 encryption algorithm. A published paper, expected to be delivered at the upcoming USENIX Security Symposium next month in Washington, D.C., describes new attacks against RC4 that allow an attacker to capture a victim's cookie and decrypt it in a much shorter amount of time than was previously possible. The paper "All Your Biases Belong To Us: Breaking RC4 in WPA-TKIP and TLS," written by Mathy Vanhoef and Frank Piessens, explains the discovery of new biases in the algorithm that led to attacks breaking encryption on websites running TLS with RC4, as well as the WPA-TKIP, the Wi-Fi Protected Access Temporal Key Integrity Protocol.

NSA releases Linux-based open source infosec tool - Security - News - iTnews.com.au
http://www.itnews.com.au/News/406509,nsa-releases-linux-based-open-source-infosec-tool.aspx

Earthquake Retrofit writes: The NSA's systems integrity management platform — SIMP — was released to the code repository GitHub over the weekend. NSA said it released the tool to avoid duplication after US government departments and other groups tried to replicate the product in order to meet compliance requirements set by US Defence and intelligence bodies. "By releasing SIMP, the agency seeks to reduce duplication of effort and promote greater collaboration within the community: the wheel would not have to be reinvented for every organisation," the NSA said in a release.
