neo user tried by:
dd if=/dev/zero of=/home/neo/somefile bs=1024 count=70
files created successfully. Again neo tried to create file having 70K using following command:
dd if=/dev/zero of=/home/neo/somefile bs=1024 count=70
But he is unable to create the file. Make the user can create the file less then 70K.
Answer and Explanation:
Very Tricky question from redhat. Actually question is giving scenario to you to implement quota toneo user. You should apply the quota to neo user on /home that neo user shouldn’t occupied space more than 70K.
1. vi /etc/fstab
LABEL=/home /home ext3 defaults,usrquota 0 0 ¨¤ To enable th quota on filesystem you should mount the filesystem with usrquota for user quota and grpquota for group quota.
2. touch /home/aquota.user ¨¤Creating blank quota database file.
3. mount -o remount /home ¨¤ Remounting the /home with updated mount options. ou can verify that/home is mounted with usrquota options or not using mount command.
4. quotacheck -u /home ¨¤ Initialization the quota on /home
5. edquota -u neo /home ¨¤ Quota Policy editor See the snapshot
Disk quotas for user neo (uid 500):
Filesystem blocks soft hard inodes soft hard
/dev/mapper/vo-myvol 2 30 70 1 0 0
Can you set the hard limit 70 and soft limit as you think like 30.
Verify using the repquota /home command.
25.CORRECT TEXT
One Logical Volume is created named as myvol under vo volume group and is mounted. The Initial Size of that Logical Volume is 124MB. Make successfully that the size of Logical Volume 245MB without losing any data. The size of logical volume 240MB to 255MB will be acceptable.
400-101 pdf Answer and Explanation:
1. First check the size of Logical Volume: lvdisplay /dev/vo/myvol
2. Increase the Size of Logical Volume: lvextend -L+121M /dev/vo/myvol
3. Make Available the size on online: resize2fs /dev/vo/myvol
4. Verify the Size of Logical Volume: lvdisplay /dev/vo/myvol
5. Verify that the size comes in online or not: df -h
We can extend the size of logical Volume using the lvextend command. As well as to decrease the size of Logical Volume, use the lvresize command. In LVM v2 we can extend the size of Logical Volume without unmount as well as we can bring the actual size of Logical Volume on online using ext2online command.
26.CORRECT TEXT
Quota is implemented on /data but not working properly. Find out the Problem and implement the quota to user1 to have a soft limit 60 inodes (files) and hard limit of 70 inodes (files).
Answer and Explanation:
Quotas are used to limit a user’s or a group of users’ ability to consume disk space. This prevents a small group of users from monopolizing disk capacity and potentially interfering with other users or the entire system. Disk quotas are commonly used by ISPs, by Web hosting companies, on FTP sites, and on corporate file servers to ensure continued availability of their systems. Without quotas, one or more users can upload files on an FTP server to the point of filling a filesystem. Once the affected partition is full, other users are effectively denied upload access to the disk. This is also a reason to mount different filesystem directories on different partitions. For example, if you only had partitions for your root (/) directory and swap space, someone uploading to your computer could fill up all of the space in your root directory (/). Without at least a little free space in the root directory (/), your system could become unstable or even crash. You have two ways to set quotas for users. You can limit users by inodes or by kilobyte-sized disk blocks. Every Linux file requires an inode. Therefore, you can limit users by the number of files or by absolute space. You can set up different quotas for different filesystems. For example, you can set different quotas or users on the /home and /tmp directories if they are mounted on their own partitions. Limits on disk blocks restrict the amount of disk space available to a user on your system. Older versions of Red Hat Linux included LinuxConf, which included a graphical tool to configure quotas. As of this writing, Red Hat no longer has a graphical quota configuration tool. Today, you can configure quotas on RHEL only through the command line interface.
1. vi /etc/fstab
/dev/hda11 /data ext3 defaults,usrquota 1 2
2. Either Reboot the System or remount the partition. Mount -o remount /dev/hda11 /data
3. touch /data/aquota.user
4. quotacheck -ufm /data
5. quotaon -u /data
6. edquota -u user1 /data and Specified the Soft limit and hard limit on opened file.
To verify either quota is working or not:
Soft limit specify the limit to generate warnings to users and hard limit can’t cross by the user. Use the quota command or repquota command to monitor the quota information.

VMware Improves Current Data Center and Cloud Security

December 8, 2017 No Comments

Vmware,inc is a global leader in cloud infrastructure and business mobility, and carbon black, the leading company for next-generation endpoint security, announced today that expanding partnerships will help transform the current cloud and data center security approach. VMware as a global leader in cloud infrastructure and business mobility, VMware helps customers realize the possibilities by speeding up the digital transformation. With VMware Solutions, businesses are improving business agility through modern applications that drive innovation through the modernization of data centers and the integration of public clouds, creating a great experience for digital workspaces and protecting customer trust by changing security. Add its management software to its mixed cloud bundle Cloud Foundation. Carbon Black and VMware will provide a new security model for secure complementary components that can be combined to take advantage of the unique attributes of virtualization and cloud to help protect previously impossible organizations.

VMware

These companies have developed a new joint solution that can significantly reduce the attack surface of the organization while enabling the security team to automatically detect and repair threats that allow OVH and IBM to use Cloud Foundation to stand on the public VMware Cloud, and realize VMware’s vision of the same software packages that run locally and in the cloud to easily move data and applications to respond to attacks faster and more efficiently. Today’s announcement expands the collaboration announced earlier this year to enable VMware Appdefense™ customers to leverage the carbon Black’s Predictive Security Cloud ™ (PSC) reputation service.

VMware now adds VMware vrealize automation,vrealize operations and Vrealize Log insight to Cloud Foundation. Because as applications become more fragmented and dynamic, they become increasingly difficult to protect. Traditional security solutions are not flexible enough to keep up with changes in the application, resulting in security issues. Most of today’s attacks are not simple malware and are easily disturbed by the “known bad” signatures. They depend on the executable file, process, and operating system of the attacker manipulating the endpoint itself. Identifying these threats requires an in-depth understanding of application behavior and threat behavior, which is not available in traditional endpoint security products.

VMware

The new joint development solution will combine VMware appdefense and CB Defense Advanced Threat Protection features to provide unique, killing and killing effects for applications within the datacenter. VMware Appdefense leverages the power of the virtual infrastructure to create the least privileged environment around the application. It enforces system integrity using a management program, provides visibility of the expected state and behavior of the application, and monitors the status and behavior of protected locations. The CB defense running on the predictive security cloud provides a next-generation endpoint protection solution that uses behavioral methods to detect threats. It uses streaming protection to monitor malicious behavior on your computer to prevent malicious software and non-malware attacks.

VMware also updated NSX to support pivotal Cloud Foundry. This means that the nsx-t,vmware, in addition to the vsphere management process, can now be used with the three cloud native frameworks of Kubernetes,openshift and cloud foundry. Pivotal announced yesterday that it would support NSX to join Cloud Foundry 2.0, in return for their favor. The new version of Cloud Foundry will also include the upcoming server-free Computing tool “Pivotal Function Service”, which can trigger activities based on data sent by users or mail systems such as RABBITMQ or Apache Kafka.

VMware

Three key elements to enhance the security of the cloud and data center:

Reinforce known good application behavior: By leveraging the virtual infrastructure, the solution will have an authoritative understanding of how the data center endpoint behaves and the first one to know when to make changes. This contextual intelligence eliminates the determination of the processes in a given datacenter endpoint, which changes to the executable file and operating system are legitimate, and which represent real threats.

Detect unknown threats: The solution will take advantage of the application context to perform advanced behavioral threat detection to provide additional protection beyond the minimum privilege. Carbon Black’s streaming prevention is a next-generation threat detection technology that uses event flow processing to correlate multiple events over time to indicate a threat, preventing application behavior from being compromised. The user can see the threat activity in real time, the visual attack chain to see what the attacker is trying to do and immediately respond to close the attack in progress.

Automated and coordinated response: Once a threat is identified, the solution will allow for a full understanding of the application context during the survey process and again use the virtual infrastructure to provide a range of responses from pausing or snapshot virtual machines to isolating damaged machines and conducting forensics analysis.

VMware

Reducing the attack surface is synonymous with reducing risk, but many organizations do not have the resources to evaluate, plan, deploy, and run application control. Appdefense uses machine learning algorithms to mitigate this operational burden while reducing risk and minimizing privileges. With this new joint solution from carbon black and VMware, the company will be able to provide customers with CB defense to detect and respond to application threats that may evade minimal privileges.

Cloud computing and virtualization provide new security opportunities beyond traditional approaches. Carbon Black and VMware’s unique capabilities beyond the point of security solutions provide organizations with a stronger, more comprehensive approach to protecting mission-critical applications that run in data centers. We look forward to the opportunity to help businesses around the world run more 60 million of virtual machines to the highest level of security.

With this new joint solution, VMware’s products can enhance system integrity and minimal permissions on data center endpoints, critical applications and data are safe for both malware and malware attacks, and security operations will be authorized to react faster and more efficiently than ever before.
