High Vulnerabilities Vulnerability Summary for the Week of April 26, 2021 The vulnerabilities are based on the CVE vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. The division of high, medium, and low severities correspond to the following scores: • High - Vulnerabilities will be labeled High severity if they have a CVSS base score of 7.0 - 10.0 • Medium - Vulnerabilities will be labeled Medium severity if they have a CVSS base score of 4.0 - 6.9 • Low - Vulnerabilities will be labeled Low severity if they have a CVSS base score of 0.0 - 3.9 Entries may include additional information provided by organizations and efforts sponsored by Ug-CERT. This information may include identifying information, values, definitions, and related links. Patch information is provided when available. Please note that some of the information in the bulletins is compiled from external, open source reports and is not a direct result of Ug-CERT analysis.

  • Sentry: a Multipourpose GNU/Linux
    last update: 25/ october / 2002 Sentry: a multipourpose GNU/Linux... [In this short article I'll try to explain how to made a good use of Sentry: an useful GNU/Linux distribution that can be considered like a swiss-knife tool. I'll also describe my setup experience with this distro (followed by a case-study to solve an inusual need).] What's sentry: As described in product's FAQ the "Sentry Firewall CD" is a bootable GNU/Linux based CD-ROM, useful for a number of different needs: from firewall to application server. What is meant for bootable CD-ROM is a media that contains an Operative System full installation and has a boot sector so, if PC BIOS allow it (and most recent ones do), it is possible to start PC directly from CD-ROM. The advantage to operate from CD is due, before all, to the unchangeability of the media and the consequent fast recovery of system. And therefore is impossible for a cracker (not "haker" as some newspaper define those informatical intruders) to destroy the system itself in a definitive way. One of preferred activities of cracker is, infact, the installation of a rootkit as soon as an host ahs been compromised. A root kit is, in simple words, a kit of modified programs and system utilities that allow an easy access to compromised system masking, at the same time, crackers activities. As You can understand these programs were, usually, installed on the compromised system hard disk and are very hard to remove so often is required to reinstall all system to gain a new safe situation.

    Les distributions Par son mode de diffusion particulier, Linux est parfois déroutant. En effet, on ne se procure jamais le système Linux mais un système Linux. Chacun est libre d’assembler son propre système Linux et de le distribuer, gratuitement ou non.

    Správa serverů a počítačových sítí 2020/2021 Přednáška č.3 ( ver. 2021-03-02-1 ) 1 / 27 4. Zálohy napájení ● Výpadek elektřiny nejde ovlivnit ani předpo- vědět – většinou ● Nekorektní ukončení systému může vést k poškození dat ● neuzavřené soubory ● pidy starých procesů ● Nemusí se zapsat data z cache ● Důvodem výpadku napájení: ● Porucha na zdroji ● Výpadek el. energie 2 / 27 4.1. Redundantní zdroj napájení ● Vznikne „špička“ v sítí a dojde ke spálení zdroje a následně k nekorektnímu ukončení systému ● Řešením je použití stroje s dvěma a více zdroji, ideálně hot-plugovými ● U dražších značkových serverů obvyklé ● Více náročné stroje potřebují pro svůj chod více než jeden ze zdrojů – například disková pole 3 / 27 4.2. UPS ● Zařízení sloužící jako záložní zdroj pro pří- pad výpadku energie ● Tři typy: ● Off-line – používá relé, nemá filtry, nereguluje na- pětí ● Line-interactive – dokáže omezeně vyrovnávat kolísání v el. síti ● Online – vyšší cena, používá filtry, velmi vý- hřevné, ale bezpečné, nepřepíná zdroj, ale funguje stále z baterií 4 / 27 4.2. UPS ● Klasicky umí ● Překlenout výpadek napájení ● Číst info z UPS ● Nadstandard (RS ) ● Vypnout server či skupinu serverů ● Spustit se zpožděním 5 / 27 4.3. Diesel agregát ● Využívám pro rozsáhlé systémy, kde už běžné UPS kapacitně nestačí ● Je schopen udržet v chodu celé počítačové sály ● Většinou velmi nákladné zařízení ● Cca před třemi roky způsobil opakované havarie ve všech velkých pražských hostingových centrech 6 / 27 4.3. Diesel agregát 7 / 27 5. Vzdálená správa ● Nejedná se o vzdálenou plochu Windows :) ● Jde o možnost ovládat server na nižší úrovni, tedy i ve stavu kdy nefunguje operační sys- tém ● Existuje ve dvou variantách: ● Interně řešená v serveru ● Externí řešení nezávislé na serveru 8 / 27 5.1.

AGRADECIMENTOS A todos que contribuíram para a realização e conclusão desta especialização tão profícua, aos colegas que prestaram apoio, aos professores do ARL, em especial ao prof. Joaquim e ao prof. Wilian, coordenador do curso e orientador deste trabalho respectivamente, e às empresas Universo Informática e Copagril, pelas estruturas disponibilizadas, um muito obrigado! RESUMO Este trabalho tem como objetivo apresentar algumas informações que auxiliem na identificação de dispositivos de hardware e software compatíveis com o Linux. A portabilidade em diferentes arquiteturas de hardware, aplicações e recursos de software e a possibilidade de migrar para um ambiente gráfico com o Linux são temas abordados na presente monografia. Com base em pesquisas bibliográficas foi possível identificar os principais ports de hardware, a diversidade de software para Linux e as distribuições recomendadas para desktops.
