kandi X-RAY | psad Summary

psad is a Perl library typically used in Security applications. psad has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

The Port Scan Attack Detector psad is a lightweight system daemon written in is designed to work with Linux iptables/ip6tables/firewalld firewalling code to detect suspicious traffic such as port scans and sweeps, backdoors, botnet command and control communications, and more. It features a set of highly configurable danger thresholds (with sensible defaults provided), verbose alert messages that include the source, destination, scanned port range, begin and end times, TCP flags and corresponding nmap options, reverse DNS info, email and syslog alerting, automatic blocking of offending IP addresses via dynamic configuration of iptables rulesets, passive operating system fingerprinting, and DShield reporting. In addition, psad incorporates many of the TCP, UDP, and ICMP signatures included in the Snort intrusion detection system. to detect highly suspect scans for various backdoor programs (e.g. EvilFTP, GirlFriend, SubSeven), DDoS tools (Mstream, Shaft), and advanced port scans (SYN, FIN, XMAS) which are easily leveraged against a machine via nmap. psad can also alert on Snort signatures that are logged via fwsnort, which makes use of the iptables string match extension to detect traffic that matches application layer signatures. As of the 2.4.4 release, psad can also detect the IoT default credentials scanning phase of the Mirai botnet.

QUESTION

SQL Query to identify records applicable for a distinct set of data

Asked 2017-Aug-11 at 07:30

I have the following query that returns the result as shown below the query. However, I need only a subset of this data. I am interested in fetching DocumentIDs that are associated to RegionID value of 2 ONLY and not associated to any other region.

  SELECT D.DocumentID, R.RegionID, COUNT(*) AS NUMOFPLANTSBYREGION 
    FROM Document D 
    INNER JOIN ShopAreaDoc SAD ON D.DocumentID = SAD.DocumentID 
    INNER JOIN PlantShopAreaDoc PSAD ON SAD.ShopAreaDocID = PSAD.ShopAreaDocID 
    INNER JOIN Plant P ON PSAD.PlantID = P.PlantID 
    INNER JOIN Region R ON P.RegionID = R.RegionID

QUESTION

RGB data sent from python program not recieving right by arduino

Asked 2017-Mar-26 at 15:09

I am working on a twitter mood light and have arduino and python code. After losing all my python code, it had to remake it from memory, but i had some problems. The python code is sending rgb data to the arduino to change an rgb led's color. For some reason though, the arduino is not picking up the last value and is changing the second value to the blue led.

For example: I sent 50,50,50 which is a dim white, and the led shows purple (blue and red) and if i send 0,0,255 (blue on) it stays blank and if i send 0,255,0 (green on) it shows blue.

I have no idea have have tried so many things to get it to work.

Python code: I know i am sending the data twice it is the only way the send function works

Stupid mistake. I had the second comma index be exactly where the first one was (oops) in the arduino code

Install psad

Depending on the Linux distribution, psad may already be available in the default package repository. For example, on Debian or Ubuntu systems, installation is done with a simple:.
Bit::Vector
Date::Calc
IPTables::ChainMgr
IPTables::Parse
NetAddr::IP
Storable
Unix::Syslog
The main requirement for an iptables configuration to be compatible with psad is simply that iptables logs packets. This is commonly accomplished by adding rules to the INPUT and FORWARD chains like so:. The rules above should be added at the end of the INPUT and FORWARD chains after all ACCEPT rules for legitimate traffic and just before a corresponding DROP rule for traffic that is not to be allowed through the policy. Note that iptables policies can be quite complex with protocol, network, port, and interface restrictions, user defined chains, connection tracking rules, and much more. There are many pieces of software such as Shorewall and Firewall Builder, that build iptables policies and take advantage of the advanced filtering and logging capabilities offered by iptables. Generally the policies built by such pieces of software are compatible with psad since they specifically add rules that instruct iptables to log packets that are not part of legitimate traffic. Psad can be configured to only analyze those iptables messages that contain specific log prefixes (which are added via the --log-prefix option), but the default is for psad to analyze all iptables log messages for evidence of port scans, probes for backdoor programs, and other suspect traffic.
