RES_FSIZE – максимальный размер файла в байтах. Deny mknod ON – запрет на использование mknod. This tool will scan and diagnose, then repairs, your PC with patent pending technology that fix your windows operating system registry structure. Logging options Определяем параметры протоколирования. http://qtechnology.net/error-opening/error-opening-vlc-exe.html

You can go ahead and set the custom profile in the kernel config and setup the system as you like. In most cases, the application is intentionally doing dynamic machine code generation and just needs an exception. Thank you. Novice Computer User Solution (completely automated): 1) Download (Error Opening /etc/grsec/pw) repair utility. 2) Install program and click Scan button. 3) Click the Fix Errors button when scan is completed. 4)

There are still a few errors in the logs. TPE prevents users from executing any file writeable by a non-root user. Use legacy ELF header marking ON – позволяет управлять опциями PaX с помощью утилиты chpax, доступной по адресу http://pax.grsecurity.net. Флаги управления будут читаться из зарезервированной части заголовка ELF-файла. Эта маркировка имеет It will slightly improve the isolation of services running as non-root while not getting in anyone's way.

He recently started a consultancy providing cost-effective open source solutions to small businesses. Restarting the sshd service is a good idea too. # gradm -a admin Password: # emerge -avuDN vim Notice that nothing is logged in the grlearn.log file. The RBAC system is running flawlessly! Randomize ET_EXEC base ON.

System packages need only to be installed under the role of admin. When you believe you have used your system sufficiently to obtain a good policy, let gradm process them and propose roles under /etc/grsec/learning.roles: # gradm -D # gradm -F -L /etc/grsec/learning.log The remaining audit features are currently disabled by default due to the high number of false positives, but can be enabled via sysctl. Consider a situation where the role is "username", while the subject is /usr/lib/firefox/firefox.

The kernel.grsecurity.audit_group switch can be set to 1 to limit kernel.grsecurity.audit_chdir and kernel.grsecurity.exec_logging to users in the audit group as they will generate a LOT of log messages. d Allow deletion of the file/directory. Emulate trampolines OFF – некоторые программы и библиотеки по той или иной причине пытаются выполнить специальные небольшие куски кода, находящиеся внутри невыполнимой страницы памяти. Наиболее известные примеры – сообщения о коде By default, many of the user-facing features are disabled, but there is significant hardening of the kernel itself against exploitation.

Let's look at the errors and fix them # gradm -E Duplicate object found for "/lib64" in role shutdown, subject /, on line 257 of /etc/grsec/policy. "/lib64" references the same object Protect outside processes ON – запрет на посыл спецсигналов процессам вне chroot. Along with the various filesystem and network protections, grsecurity also provides a role-based access control system that uses a least privilege approach to running processes. In fact, it's a good idea to start with the low setting and see how things go.

The grsecurity wikibook is written by the creator(Bradley Spengler) of the subject in discussion. his comment is here Contents 1 Installation 1.1 Custom kernel 2 Compatibility 3 PaX 4 Configuration 5 Trusted path execution 5.1 Using the tpe group as a whitelist or blacklist 5.2 Compatibility 5.3 Partially restrict The corrupted system files entries can be a real threat to the well being of your computer. After that, of course, the previous content won't be recoverable.

The following features are enabled in /etc/sysctl.d/05-grsecurity.conf by default and are unlikely to cause any compatibility issues: kernel.grsecurity.chroot_deny_fchdir = 1 kernel.grsecurity.chroot_deny_shmat = 1 kernel.grsecurity.chroot_deny_sysctl = 1 kernel.grsecurity.chroot_deny_unix = 1 kernel.grsecurity.chroot_enforce_chdir = If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Chdir logging OFF – протоколирование всех вызовов chdir() (смена каталога). (Un)Mount logging OFF – протоколирование монтирования и размонтирования файловых систем. http://qtechnology.net/error-opening/error-opening.html Single group for auditing OFF – эта опция позволяет выводить информацию о конкретном пользователе или группе. Удобно в случае слежения за конкретным пользователем или группой.

Beginning full learning subject reduction for user sshd...done.

Enforce RLIMIT_NPROC on execs ON – для пользователей с ограничениями на количество процессов значения этих ограничений будут проверяться в процессе вызова execve(). Без этой опции система будет проверять значения ограничений только x This object can be executed (or mmap'd with PROT_EXEC into a task). In the beginning of the policy file, there are lot of details about the present RBAC system, read them. With this approach, a process runs with the lowest privileges required to complete its task.

There can be many events which may have resulted in the system files errors. A Role determines what user the ruleset applies to, while the Subject could be seen as what process/program the ruleset applies to. i This mode only applies to binaries. Number of messages in a burst (maximum) 4 – максимальное число сообщений, регистрируемое за время, определенное предыдущей опцией. Компилируем ядро, перегружаемся. Конфигурирование Подготовительный этап закончен, теперь разберем конфигурацию GRSecurity. Центральным понятием

There are various modes here too. PaX is a separate but bundled project that provides address space protection. In addition to the grsecurity section, you will also notice a section for PaX.
