Pacman and security

A better packet system with security.
Twoday all mirrors distrubute a file with all checksums for the mirror, witch can be used to werify that the packet isent corupted in transfer. The security problem her is that if a packet is replaced, whith a backdoord version, on the mirror the checksum file can be replaced to, whitch means that the client will install the corupted packet without any warnings.
So how do we solve this?
Well, one solution whud be to digitaly signe the packet list with a private key (PGP) and then decrypt it with a public key thats not from the mirror. If we do this then we can garentue that all packets is the same as when it was distrubuted to the mirror, and that the packet hasent been corupted in transfer.
Distrubution of the public key.
Ther is multipel ways of distrubution the public key for the packet list, but what's important is to NOT distrubute it thrue the mirrors. If one mirror is compromesed then the key cude be replaced.
One way to distrubute it is to staticly compile it into pacman, this whud make it mutch secure, but its not werry practical. For example, if we want to replace the key, we must upgrade all pacman binarys.
The second way is to distrubute it thrue the homepage and let all users get it from ther.
We nead security in a packet system, especaly when the dist is growing.
This is just a ide, think on it!
PS. Sorry for my bad spelling DS.

Start up problems after Safari 3.1 and Security update

Updated safari and security update last night.
Safari downloaded and installed but there was an error downloading or installing the security update, I forgot.
After I restarted everything booted up fine, but was stuck on "Starting Mac OS X" screen.
Did a fsck and zap the pram, still stuck.
Today I tried booting up in safe mode, stuck on the gray screen with the apple logo.
Then I tried booting up from an external firewire dvd drive. Repaired permissions, repaired the disk, but it is still stuck on "Starting Mac OS X" screen. Help please...
Thank you

Ok i had a similar problem, with all the recent updates for Leopard, including the 10.5.2 combo update... the 12" PowerBook G4 kept getting stuck on the grey apple and spinning wheel... if it managed to get past this it would get stuck on the blue screen!!!
The way i got around this, after trying all these other tips was: Archived & Installed 10.5; restarted, waited; downloaded 10.5.2 Combo update, installed; restarted, waited; waited; waited; after getting back to desktop, restarted, waited; then ran Software Update only installing one at a time, and after each install, restarted, waited; when all Software updates completed, proceeded with iLife updates etc... It took a while (still quicker than the 3 days of failed installs and updates) with a lot of waiting on the blue screen (5-20mins) but we got there in the end. Disks where checked with Leopard Disk Utility before and after, permissions where checked before and after completing all installs, also with a DW 4.1 optimization. Also note worthy is the RAM was upgraded from the initial 256Mb (!!!) with an extra Gb.

Bursting with translation and security attributes?

Hi folks,
I've been lurking on the forum for a while and despite not always finding a solution, existing threads normally pointed me in the right direction - so thanks :)
I'm working on EBS 11.5.10 with the latest Bi-Publisher 5.6.3 (5472959) and bursting (5968876) patches installed.
I have successfully done the following individual AR Invoice Bi-Publisher tasks:
1. translated an invoice RTF template by attaching an xliff file to the data definition,
2. applied security attributes to the template to restrict updates on the resulting PDF,
3. burst a custom AR invoice print and emailed the resultant pdf's.
The PDF generated by the combined Invoice print correctly applies the translation and security attributes; however when I run the "XML Publisher Report Bursting Program" to the XML file the resultant burst PDF's do not apply the translation or security attributes. I assume this a limitation of bursting control files? If so, is this on the list of future enhancements to Bi-Publisher?
Here's an example of my control file document entry, I have included locale and pdf-security entries - these don't cause an error but equally don't generate the desired result (p.s. I know I'm emailing on a PRI filter - it's just a test):
<xapi:document output-type="pdf" delivery="att_email">
<xapi:template type="rtf"
location="/usr/tmp/xxxINVOICE3.rtf"
locale="fr-US"
pdf-security="true" pdf-encryption-level="1" pdf-permissions-password="xxxxxx"
filter=".//G_INVOICE_HEADER[PRINTING_OPTION='PRI']" >
</xapi:template>
</xapi:document>
Thanks
Dave

You would have happened to try applying the security stuff in the application for your template? Try that and see if the pdf properties get set.
If that doesn't work your left with two options:
1. create a java concurrent program and set the properties manually.
2. Log a tar.
=================
==local idea's
=================
Are you sure you don't have to create template config for the locale? i suspect that's why it's not applying the xliff translation. Also, your NLS_LANG needs to be set to FRENCH for the approriate template to be applied. If your logged-in as english your french format template will not be applied, neither will the translation. As an example you can query vl table and you'll only get american (us) but if you alter your session you'll get the translation for that language when your query the table.
location="xdo://xxxAR.xxx_XML_PRINT.fr.US"
try it out and see if that works. Note: This will only work if your session NLS_LANG is set to FRENCH.

How to Set up HTTPOnly and SECURE FLAG for session cookies

Hi All,
To fix some vulnerability issues (found in the ethical hacking , penetration testing) I need to set up the session cookies (CFID , CFTOKEN , JSESSIONID) with "HTTPOnly" (so not to access by other non HTTP APIs like Javascript). Also I need to set up a "secure flag" for those session cookies.
I have found the below solutions.
For setting up the HTTPOnly for the session cookies.
1] In application.cfc we can do this by using the below code. Or we can do this in CF admin side under Server Settings » Memory Variables
     this.sessioncookie.httponly = true;
For setting up the secure flag for the session cookies.
2] In application.cfc we can do this by using the below code. Or we can do this in CF admin side under Server Settings » Memory Variables
     this.sessioncookie.secure = "true"
Here my question is how we can do the same thing in Application.cfm?. (I am using ColdFusion version 10). I know we can do this using the below code , incase of HTTPOnly (for example).
<cfapplication setclientcookies="false" sessionmanagement="true" name="test">
<cfif NOT IsDefined("cookie.cfid") OR NOT IsDefined("cookie.cftoken") OR cookie.cftoken IS NOT session.CFToken>
<cfheader name="Set-Cookie" value="CFID=#session.CFID#;path=/;HTTPOnly">
<cfheader name="Set-Cookie" value="CFTOKEN=#session.CFTOKEN#;path=/;HTTPOnly">
</cfif>
But in the above code "setclientcookies" has been set to "false". In my application (it is an existing application) this has already been set to "true". If I change this to "false" as mentioned in the above code then ColdFusion will not automatically send CFID and CFTOKEN cookies to client browser and we need to manually code CFID and CFTOKEN on the URL for every page that uses Session. Right???. And this will be headache.Right???. Or any other way to do this.
Your timely help is well appreciated.
Thanks in advance.

You can switch httponly / secure on and off, as we have done, for CFID and CFToken. However, Tomcat automatically switches JsessionID to 'secure' when it detects that the protocol is secure, that is, HTTPS.
I couldnt understand this. I mean how are you relating this with my question.
When Tomcat detects that the communication protocol is secure (that is, HTTPS), it automatically switches on the 'secure' flag for the J2EE session cookie, JsessionID. Tomcat is configured to do that. Coldfusion has no say in it. So, for JsessionID, 'secure' is automatically set to 'false' when HTTP is detected and automatically set to 'true' when HTTPS is detected.
     If this is the case then why I am getting below info for jsessionid (As you mentioned it should set with SECURE flag . Right???). Note that we are using web server - Apache vFabric .And the application that we are using is in https and there is no hit is going from https to http.

Set HTTPOnly / Secure for the session cookies that you wish to use. Each cookie has its pros and cons. For example, the JsessionID cookie is more secure and more Java-interoperable than CFID/CFToken but, from the explanation above, it forbids the sharing of sessions between HTTP and HTTPS.
     I understood that setting thos flags (httponly/secure) is as per my wish. But my question was , is it necessary to set those flags forcf session cookies (cfid and cftoken) as we have enabled J2EE session in CF admin?. Or in other way as the session management is J2EE based do we need to set those flags for CF session cookies?.
BKBK wrote:
3]If I need to set HTTPOnly and SECURE flag for JSESSIONID , how can I do that.
It is sufficient to set the HTTPOnly only. As I explained above, Tomcat will automatically set 'secure' to 'true' when necessary, that is, when the protocol is HTTPS.
     I understood that it is sufficient to set httponly only.but how we will set it for jsessionid?. This is my question. Apache vFabric will alos set secure to true automatically. Any idea??

Why not just run the ThinkVantage System Update and let it install as usual. You can also "un-check" those drivers that you don't want to install.

"logon time" between USR41 and security audit log

Dear colleagues,
I got a following question from customer for security audit reason.
> 'Logon date' and 'Logon time' values stored in table USR41 are exactly same as
> logon history of Security Audit Log(Tr-cd:SM20)?
Table:USR41 saves 'logon date' and 'logon time' when user logs on to SAP System from SAP GUI.
And the Security Audit Log(Tr-cd:SM20) can save user's logon history;
at the time when user logged on, the security audit log is recorded .
I tried to check SAP GUI logon program:SAPMSYST several ways, however,
I could not check it because the program is protected even for read access.
I want to know about specification of "logon time" between USR41 and security audit log,
or about how to look into the program:SAPMSYST and debug it.
Thank you.
Best Regards.

Hi,
If you configure Security Audit you can achieve your goals...
1-Audit the employees how access the screens, tables, data...etc
Answer : Option 1 & 3
2-Audit all changes by all users to the data
Answer : Option 1 & 3
3-Keep the data up to one month
Answer: No such settings, but you can define maximum log size.
4-Log retention period can be defined.
Answer: No !.. but you can define maximum log size.
SM19/SM20 Options:
1-Dialog logon
You can check how many users logged in and at what time
2-RFC login/call
Same as above you can check RFC logins
3-Transaction/report start
You can see which report or transaction are executed and at what time
(It will help you to analyise unauthorized data change. Transactions/report can give you an idea, what data has been changed. So you can see who changed the data)
4-User master change
(You can see user master changes log with this option)
5-System/Other events
(System error can be logged using this option)
Hope, it clear the things...
Regards.

I have used a Seagate external hard drive for my Mac desktop. It is malfunctioning. Can I disconnect and depend on iCloud to keep my documents, music, and photos backed up safe and secure? I use the Cloud for phone, pad and desktop.

Can I expect iCloud to safely back up and secure my documents, music and pictures? I am using Cloud on phone, pad, and desktop. Have depended on external hard drive in the past. It is malfunctioning. Will the Cloud replace it for storage and safety?

Time Machine in itself, without an external drive may well be good for instances where you accidentally delete documents that you later require. However in the event of a hard drive failure, if Time Machine backup is kept on the same drive as the original items, it will not be much use to you.
In my opinion, it is vitally important that you have an external drive for backup, whether you use Time Machine or a another backup solution is entirely up to you.
My situation is slightly unusual, I have four hard drives in my computer and multiple arrays of hard drive enclosures with multiple hard drives within them (in total I have 40 TB of storage). As a result of this I tend to employ more than one backup procedure, I use Time Machine to backup some items and a utility called tri-backup to backup other items. I also keep two backups of everything.
Time Machine is free, it's included with your operating system, I wonder if you mean time capsule.

Unable to Reboot After Latest Apple Updates (SA-2011-06-23-1 and Security Update 2011-004)

Hi All,
After applying today's updates (06/23/2011) in APPLE-SA-2011-06-23-1 Mac OS X v10.6.8 and Security Update 2011-004, my MacBook will no longer boot. Prior to updating, the MacBook workked perfectly (except for the occasional error entry in the system and kernel log). The MackBook model number is A1278, with a RAM upgrade (4 GB).
When booting in NORMAL mode, the grey screen with Apple logo (and spinning wheel) is shown for about 50 seconds. The device never shows the blue background or login window. It simply shuts down like the power was pulled.
When booting in SAFE mode, the grey screen with Apple logo (and spinning wheel) is shown for about 1 minute 30 seconds. The blue background is shown and quickly transitions to the login windows. About 45 seconds after the login window is shown, the machine shuts down like the power was pulled.
On the few occassions I logged in to take advantage of the 45 second safe mode window (before shutdown), I was *not* able to copy off my log files (in /log/var) to a thumb drive because the computer would not mount the USB device.
When I peeked at the system's log file, I caught the tail end of "signature validation failed" for a bunch of hardware - from video to audio. I can only peek because the computer will shutdown before I have an opportunity to study anything in detail. The failed verifications may or may not be related to the shutdown - signature verfication might be disabled in safe mode; I simply don't know.
It seems the world's most advanced operating system [tm] is performing the world's most epic failure. Any ideas to get this brick working again would be greatly appreciated.

Here's what I've found:
(1) I cannot run Disk Utility because I don't have my install disk handy
(2) I cannot run Repair Permissions because Apple does not make a separate ISO available to fix their mistakes
(3) There does not appear to be a wat to back out updates (ie, no Add/Remove Programs)
I was able to boot into safe mode and perform:
> sudo bash
$ chmod -R root /
Amazingly, the command ran to completion. Unfortunately, it did not fix the problem. As soon as some spare cycles were available (interesting indeed!), the machine shutdown.
+1 to Apple engineers for creating a broken patch
+1 to Apple quality assurance for letting the junk out the door
+1 to Apple, for not offering an ISO to fix a broken installation
+1 to Steve, who has managed to keep his anti-trust lock on the hardware and broken software
Great job, Apple

Is there a way to view Flash videos on my iMac without downloading Adobe Flash Player? I'm concerned about performance and security with Adobe Flash Player.

If the video is only available in a format that requires Flash player : then no.
However, a great many can also be viewed in an HTML5 version, in which case http://hoyois.github.io/safariextensions/clicktoplugin/ or similar can be set up so that Flash never runs unless you specifically choose it to.

I've searched high and low for an answer and nothing I find on-line seems to apply. I also notice that the option to 'Run as Administrator' does not work. If I right-click on cmd.exe and select 'run as administrator', the command box opens but
I am not prompted for credentials and the command box does not have admin rights. Not sure if this is related or not.
Any help on this would be greatly appreciated.

Hi,
Delete your remove action from the GPP and push it again, does this issue still occur?
If it still exists, let’s collect the GPP log for analysis:
Group policy Preference debug logging policy settings are located under:
Computer Configuration\Administrative Templates\System\Group Policy
Click Logging and tracing, select local users and group preference logging and trace.
Meanwhile, just a similar issue, but it is worth trying:
A user is added to the wrong group on a client computer that is running Windows 7 or Windows Server 2008 R2
