The purpose of this section is to provide a brief overview of the subject, a list of documents and scripts for disabling SUID files is provided. See It would be useful to have packages that reset the SUID files for examples situations such as Bastion Hosts (high), multi-user servers (medium), workstations (low).So reboot after applying patches, check carefully that no unexpected daemons are running and consider re-running Jass (it is designed to allow multiple runs). Improving Disksuite Security: Disksuite is a tool bundled with Solaris that allows disks to be mirrored or gathered into RAID sets. The problem is that Disksuite uses RPC (specifically: two programs ## Prune syslog logs weekly, keeping the last 6 months or so: 55 23 * * 6 /secure/rotate_log -n 40 alertlog 55 23 * * 6 /secure/rotate_log -n 40 authlog 55 23 * * 6 /secure/rotate_log -n 20 cronlog 55 23 * * 6 /secure/rotate_log -n 40 daemonlog 55 23 * * 6 /secure/rotate_log -n 40 kernlog 55 23 * * 6 /secure/rotate_log -n 40 local0log 55 23 * * 6 /secure/rotate_log -n 40 local2log 55 23 * * 6 /secure/rotate_log -n 40 local5log 55 23 * * 6 /secure/rotate_log -n 20 newslog 55 23 * * 6 /secure/rotate_log -n 40 userlog 55 23 * * 6 /secure/rotate_log -n 10 lprlog 55 23 * * 6 /secure/rotate_log -n 20 maillog # Solaris 2.x logs: 0 4 * * 6 /secure/rotate_log -L /var/adm -n 30 loginlog 0 4 * * 6 /secure/rotate_log -L /var/adm -n 30 sulog 0 4 * * 6 /secure/rotate_log -L /var/adm -n 2 0 4 * * 6 /secure/rotate_cron (you may prefer NTP, it's more accurate, but complex, uses bandwidth and is an additional security worry). ## Synchronise the time: 0 * * * * /usr/bin/rdate YOURTIMEHOST Files which have the SUID bit set (an "s" where the execute bit for the owner/group is shown in 'ls' listings) allow the user executing the program to assume the identity/group of the owner of the program.RPC services should be avoided on sensitive servers, such as those on the Internet or in a DMZ. This is typically used to allow normal users to access certain function typically only allowed to root, for example binding to low ports, mounting a floppy disk, etc.The commercial tripwire allows signing of the tripwire database, which makes it more secure. The primary goal behind the development of the Solaris Security Toolkit ("Jass") was to simplify and automate the process of securing Solaris systems through Jump Start or in a standalone mode.Depending on the function of the server, applications such as ftpd, BIND, proxies, etc. Hardening of specific applications like ftp, DNS, Email and also general application tips are discussed in a separate document Connect to the live network. It implements the recommendations in Sun's Blue Prints security articles.What is required, is a file integrity checker that uses secure (one-way) hashing algorithms.
Possible strategies are: : Patches may reverse some of Jass's changes.On the next page enter the ABOVE email address, click "SET MY OWN" and amount as 20, your name, message( part of the question) and delivery date (now) and CHECKOUT.

We apologize for the inconvenience, if you are not satisfied you can use the credit for another question in future. Important : Do not enter your email address in the "Recipient E-mail" field on next page but enter "[email protected]". initialise tripwire's database and then run regular checks to monitor for changes.If possible, keep the master database on another machine, offline or on write-once media. To automate for many hosts, this script is then called from another script for each host that needs to be monitored. This script also assumes that the commercial tripwire is used on the central trusted host (only). Have applications been tested in detail, by different people with different points of view, from different access points on the network?

Tripwire uses several secure hashing algorithms (and in it's commercial form, provides cryptographic signing of it's database).
