It is increasingly important to manage in safety today,The need that the pattern of management of UGO attributive of system of traditional Unix file cannot have satisfied daily system to supervise the work.And ACL mechanism gradually the attributive management pattern of predominate.A few ACL that the article basically introduced to be in those who be based on Linux2.6 kernel to issue aspirant travel of edition Fedora Core are basic functional experiment.

Fictitious the meaning that change is rich,Application is wide.Current and fictitious change a technology to basically pay close attention to atThe server is fictitious change,Provide many independent operating systems on computer of a host namely.Article general exploration is fictitious the mind that changes backside,Discuss implementation next fictitious a few technologies that change.What we still have knowledge is a few otherer fictitious change a technology,For example of the operating system on Linux fictitious change.

The premise that if why affecting usability,the article described to you issues those who accelerate Linux operating system to steer rate.Of course,This kind of method asks you reach the dependence between the service to concern to understand somewhat to systematic service,If they can run paralell,start,Make them collateral start and not be serial start.

So that environment of setting Kerberized works in coordination with Solaris(TM) 10,If why understanding configures close key to distribute a center in AIX(R) Version 5.3 (KDC) .You still will be browsed in a series of measure that client of Kerberos of the configuration in Solaris 10 carries,Be opposite in order to use AIX Version 5.3 as KDC the user of Telnet, long-range Shell (rsh) and safe Shell (SSH) undertakes identity test and verify.Individual AIX IBM Network Authentication Service (NAS) KDC is used to undertake identity test and verify between different platform very useful,In mixing an environment especially.

If where,the article was described Linux of lieutenant general of ISeries environment is installed and the setting is operating system of a client.

Logistic partition is summarized

The resource that the logistic and divisional function of ISeries makes you OK and fictitious turn a machine (memory, disk, processor) ,The OS/400 example that can go up to run many independence at the same time in same hardware so (other perhaps operating system) .

Only overcautious person just can survive,Like other sphere,In ensure Linux%26reg;When systematic safety,This word as much applicable.Fortunately,Have a lot of safe character,In perhaps compiling a kernel,In perhaps joining a lot of Linux to publish edition,The form that perhaps can use a program in order to open source code is obtained alone.Part of 2 covered detailed list to evaluate, category of risk analysis, affirmatory user and visit prerogative,And the plan of more detailed action that safety achieves Linux to publish edition and measure.

Only overcautious person just can survive,Like other sphere,In ensure Linux%26reg;When systematic safety,This word as much applicable.Fortunately,Have a lot of safe parts,In perhaps compiling a kernel,In perhaps joining a lot of Linux to publish edition,The form that perhaps can use a program in order to open source code is obtained alone.As the part of 1 of this series,The concept that the article will make you begin to understand safety and potential risk,The content ready-made that needs to know truly for you:How to protect the installation that is based on Linux with consolidate.

Study can make your Linux%26#8482;The system can resist more the technology of attack,Include protective guiding process and this locality file, add for service and tiring-room process implement quota and restriction lock, compulsively, enable compulsive visit to control (Mandatory Access Control) ,And the safe flaw that identifies those to may introduce when using new software to update safe facilities.The idea that the part of 1 of this series introduced security and potential menace.The thing that part of 2 listed when planning safe installation, need to be written down sincerely.

As manager of a network,The every network equipment that you need to need to manage for you deposits the user information that is used at management.But network equipment supports finite user management function only normally.How does study use Linux%26#8482;Server of a when go up exterior RADIUS comes user of test and verify,Specific for it is to pass server of a LDAP to undertake test and verify,The user information that can place memory to go up and undertake test and verify by RADIUS server in LDAP server centrally,The government that can reduce user management to go up already thereby pays expenses,Can make log onto a process remotely again more safe.

? ? develops as the high speed of Internet,Individual, enterprise and government sector rely on a network increasingly to pass information,However the open sex of the network and share a gender to make it is being sufferred come from the tremendous security that editor of hacker, script brings to browbeat,Distributed reject to serve attack, lead plane be accusinged the filch of sensitive information,The regular job that affected a network severely,A heat that the defence network of an on the safe side makes safe now field.Investigate its germ,It is aggressor and defence person between in the rich play chess that undertaking an asymmetry,Especially the asymmetry on information,Aggressor can use scanning, explore the information that waits for a series of technology measures to get punching bag in the round,And defence person minatory to the safety that he gets utterly ignorant,Method of the origin that although be returned after be captured,understands aggressor very hard, attack and punching bag,Sweet net technology is to turn round situation of this kind of asymmetry and put forward.
