Red Hat Enterprise Linux Update Security
Open Source as a Security Innovation 1. More eyes on the code, therefore less security bugs 2. Red Hat’s rapid response to any vulnerabilities Time from a critical issue being known to the public until the day that a fix is available via RHN Red Hat Enterprise Linux 4, Feb 2005-Feb 2006 23
Red Hat Security Certifications ● ● ● ● ● NIAP/Common Criteria: The most evaluated operating system platform ● Red Hat Enterprise Linux 2.1 – EAL 2 (Completed: February 2004) ● Red Hat Enterprise Linux 3 EAL 3+/CAPP (Completed: August 2004) ● Red Hat Enterprise Linux 4 EAL 4+/CAPP (Completed: February 2006) ● Red Hat Enterprise Linux 5 EAL4+/CAPP/LSPP/RBAC (Completed: June 2007) DII-COE ● Red Hat Enterprise Linux 3 (Self-Certification Completed: October 2004) ● Red Hat Enterprise Linux: First Linux platform certified by DISA DCID 6/3 ● Currently PL3/PL4: ask about kickstarts. ● Often a component in PL5 systems DISA SRRs / STIGs ● Ask about kickstarts FIPS 140-2 ● Red Hat / NSS Cryptography Libraries certified Level 2 24
RHEL5 Security: DoD Access Cards 25
RHEL5 Security: NIST Standards Work Extensible Configuration Checklist Description Format (XCCDF) Enumeration for configuration requirements DISA FSO committed to deploying STIG as XCCDF Others working with NIST Security policy becomes one file 26
RHEL5 Security: Basics of SELinux 27
RHEL5 Security: SELinux Policies Targeted Policy (Default) Applications run unconfined unless explicitly defined policy exists Strict Policy All application actions explicitly allowed through SELinux, else actions denied MLS Polyinstantiated file systems Allows for different “views” based on clearance level 28
RHEL5 SELinux Enhancements ● ● Expanded SELinux targeted policy coverage ● Provides coverage for all core system services, versus 11 in Red Hat Enterprise Linux 4 ● Includes support for Multi Level Security (MLS) enforcement model ● In addition to existing RBAC and TE models An additional level of protection against security exploits ● Fine-grained policies via kernel-enforced mandatory access controls ● Limits the scope of security vulnerabilities ● Beyond what any other general-purpose OS can deliver 29
RHEL5 SELinux Enhancements ExecShield This enhancement can prevent any memory that was writable from becoming executable. This prevents an attacker from writing his code into memory and then executing it Stack Smashing protection (Canary values) The system will place a canary value at a randomized point above the stack. This canary value is verified during normal operation. If the stack has been smashed, the canary value will have been overwritten, indicating that the stack has been smashed. This is a method to detect buffer overflows early. FORTIFY_SOURCE GCC option When the compiler knows the size of a buffer, functions operate on the buffer to make sure it will not overflow at runtime. This works to help catch format string flaws as well as buffer overflows. 30
RHEL5 SELinux Enhancements Loadable Policy Modules ● In the past, all policy changes had to be made to the policy source ● Required the entire policy re-compiled ● Requiring a full set of policy development tools on production systems. ● ● Modules allow for the creation of self-contained policy modules ● Safely linked together to create system policies ● Add policy on the fly ● Remove policy on the fly Framework to allow ISV/OEM partners to ship their own modular SELinux policy Further Information ● http://sepolicy-server.sourceforge.net/index.php?page=moduleoverview 31
RHEL5 SELinux Enhancements New troubleshooting tool provides clear, easy-to-understand, GUI-based, security violation notifications Over 60 events defined today 32
RHEL5 SELinux Enhancements Policy creation now a two-step process 1) system-config-selinux - Creates template policy (network, filesystem read/write, etc) 2) audit2allow - Traces application, ensuring proper accesses 33
SELinux: End-User View sealert Notification 34

SELinux: System Administrator View Using audit2allow & semanage You are experiencing SELinux errors You know that these errors are blocking legitimate usage Be aware that changes to your SELinux policy could compromise the security of your system. 37

Red Hat Enterprise Linux Update High Availability
RHEL5 High Availability: Mature Scaling 42
LVM Host-Based Synchronous Mirroring Each write is simultaneously written to 2 or more local or SAN disks (RAID1) LVM automatically detects failure, uses the identical, mirrored disks or LUN Upon restoration, recovery process begins in background If minor outage, transaction log rapidly replays missed I/O 43
Device Mapper Multipath IO (MPIO) Connects & manages multiple paths through SAN to storage array Upon component failure, MPIO redirects traffic via redundant pathing Active/Active array support Bundled into RHEL 44
GFS Red Hat GFS is an open source, POSIX-compliant, cluster file system. It provides a consistent file system image across the server nodes in a cluster, allowing Red Hat Enterprise Linux servers to simultaneously read and write to a single shared filesystem. Red Hat GFS also includes Red Hat Cluster Suite providing integrated application high availability and failover. 45
Red Hat Enterprise Linux Update Directory Server Certificate Server
Red Hat Authentication History On December 8, 2004, Red Hat acquired assets from AOL’s Netscape Security Solutions business unit, including currently shipping products: Netscape Certificate Management System (Red Hat Certificate System) Netscape Directory Server (Red Hat Directory Server) Acquisition of JBoss in June 2006 now provides an extension for the identity management technologies into the Application and Web Services space. 47
What does Red Hat Directory Server provide? Standards Compliance (LDAP v2/v3) High Performance Multi-Master Replication WAN Replication Load Balancing Data Redundancy Fault Tolerance Windows User Synchronization SASL Authentication Fine Grained ACL 48
What does Red Hat Certificate System provide? Standards Based PKI Unmatched Scalability 14,000 certificate issuances/hour 12M certificates issued < 35 days Largest public CRL: 1.2M Government Support FIPS-140 Certified EAL4/CIMC Protection Profile Replaces Passwords, Single Sign-On Smart Card Support Integrated with RHEL & Windows 49
Certificate Server Scalability 25M+ Certificates issued from the DoD PKI CAs, 1999-Present 3.5M – 4M “active” smart cards, most with 3 certificates Issuing lifetime of individual CAs governed by the size of the database managed by the CA As number of certificates issued increased, number of revocations increased, resulting in large CRLs CMS 4.2 and CMS 6.1 on Solaris – approximately 1.5M issued certificates per CA Red Hat CS 7.1 on Linux [deployed in 2006] – DT&E Testing prior to fielding demonstrated 3M issued certificates per CA with large CRL 50
PKI and Kerberos: Independently Successful PKI Smart card authentication Web services TLS, SSL Encryption Signing Data integrity Non Repudiation Asymmetric keys Kerberos System Login Secure Filesystem access NFSv4, CIFS Email server access Printing Symmetric keys Directory & Certificate Server tie them together 51

MRG: Messaging Provides messaging that is up to 100-fold faster than before Spans fast messaging, reliable messaging, large-file messaging Implements AMQP, the industry’s first open messaging standard, for unprecedented interoperability that is cross-language, cross-platform, multivendor, spans hardware and software, and extends down to the wire level Uses Linux-specific optimizations to achieve optimal performance on Red Hat Enterprise Linux and MRG Realtime ● Takes advantage of RHEL clustering, IO, kernel, and more ● Includes new high-performance AIO Journal for durable messaging ● Provides native infiniband support for transient messaging 67
About AMQP AMQP is an open specification for messaging ● It is a complete specification ● Anyone may use the AMQP specification to create useful implementations without being charged for the IP rights to do so AMQP aims to be technology and language-neutral ● Available in C, C++, Java, JMS, .NET, C#, Ruby, Python, etc. ● Requires IP, and can be used with TCP, UDP, SCTP, Infiniband, etc. Products complying with AMQP are inter-operable ● AMQP is a Wire-Level protocol based on the ubiquitous IP ● Wire-level compatibility means it can be embedded in the network ● Applications written to Product X will plug into servers running Product Y Red Hat is a founding member of the AMQP Working Group 68
MRG: Enables applications and transactions to run predictably, with guaranteed response times ● Realtime Provides microsecond accuracy Provides competitive advantage & meets SLA’s ● Travel web site: missed booking ● Program trading: missed trades ● Command & Control: life & death Provides replacement kernel for RHEL 5.1+; x86/x86_64 Preserves RHEL Application Compatibility 69
