Pat Greene is working as a network administrator at XYZ Inc.

Pat implements a directory service to store data at a centralized

location. Pat is informed that:

-The authorized users are not able to access the Directory server as

a malicious user is identifying the hardware and software environment

of the directory server.

-After identifying the capacity of the directory server, the

malicious user is sending more traffic than what the server can

handle.

Which technique does this type of attack illustrate?

SYN attack

Buffer overflow attack

Technology Systems is a leading developer of computer applications.

The organization has its head office in California and two branch

offices in New York and Toronto. There are three departments in the

organization: Marketing, Programming, and Accounting. The Programming

department is divided into two groups, Windows group and Linux group.

The branch offices are connected to the head office by a 56 Kbps

leased line. Now, each branch office runs as a separate entity, with

its own network, reporting structure, and constraints. The

organization has no centralized IT management group, and separate

administrators at each branch office manage the network. Since the

organization has multiple servers but no centralized management of

the information, it faces the data-related problems, such as data

redundancy and data inconsistency.

To avoid these data-related problems in the organization, Jim Lewis,

the system administrator at the head office, decides to install and

configure the OpenLDAP Directory service. Through the use of OpenLDAP

Directory service, Jim wants to provide authentication service in the

organization.

This authentication service authenticates the employees to the

directory server by providing the employees encrypted tickets for a

short duration. During the period when the ticket is valid, an

employee can access the directory service without providing a

password.

Now, to implement the above authentication mechanism, which

prerequisite software package must be installed and configured by Jim

before installing OpenLDAP, and what is the command entered by Jim to

install the prerequisite software package?

Red-Eye Experts is a leading developer of computer applications, with

its head office in New York. The organization has three departments:

HR, Research, and Development. A directory service is configured in

the HR department and all the employees in the rest of the

departments access the directory service. The organization has two

branch offices in London and Paris. These branch offices are

connected to the head office in New York through Virtual Private

Network (VPN). The directory service, in the HR department of the

head office, is also accessed by the employees in the branch offices.

So, there is a potential risk that a network failure between the head

office and the branch offices can seriously affect the employees in

the branch offices. To prevent this situation, John Barrett, the

system administrator at the head office, decides to create multiple

replicas of the directory service and configure these replicas in the

branch offices. Now, to maintain data consistency, John wants to

synchronize the data which is stored in the main directory service

and the replica servers. John wants to implement a mechanism in such

a way that when a replica server receives a write operation request

from a client, it performs the write operation. After that, the

replica server sends the modified updated entry values to all the

replica servers and the main server. On receiving the modified entry

values, the main server and the replica servers update the stored

entries accordingly. Now, which Replication Policy and Write

Operation performing strategy should be employed by John to implement

the above mechanism?

Single-Master Replication Policy using chaining

Multimaster Replication Policy using referrals

Multimaster Replication Policy

Red-Eye Experts is a .NET applications development organization,

based in the US. The organization uses the Windows platform for

developing .NET applications. For security reasons, Donna Bard, the

network administrator, needs to migrate .NET applications to the

Linux platform to provide file-level and user-level security to the

applications. To migrate the .NET applications to the Linux

platform, Donna needs to install the Mono tool that provides a number

of APIs that can be used to run the .NET applications on Linux. For

this, Donna installs the mono-data-1.1.6-1.novell.6.3.i586.rpm RPM

package as the first package of the tool. However, Donna finds an

error massage while installing this package. What error message does

Blue Moon Computers is a software development organization, which has

development centers all over the US. Pat Greene, the system

administrator at Blue Moon Computers, installs a LDAP server to store

the information about the employees and projects running at different

development centers. The Internet has facilitated the growth of Blue

Moon Computers. Therefore, Pat decides to increase the accessibility

of the LDAP server to all development centers through the Internet.

According to the company’s policies, the electronic mail address for

a given employee is considered public information and the employee's

home address is considered sensitive information. It must be

protected to address employee privacy concerns. Easy accessibility to

the LDAP server allows malicious users to try and access the LDAP

server to obtain the home address and other such private and

confidential information about various employees. Therefore, the

server needs to be protected against such malicious users. Pat needs

to implement Access Control List (ACL) to grant access privileges to

the authenticated users.

Which of the following options contains the access control

requirements to accomplish this task?

-Replication and synchronization

-Managing the directory server

-Network environment

-Physical security

-Directory accessibility

-Read/Write permission

-Sestivity of data

-Administration of directory server

-User community

-The subjects accessing the LDAP server

-The objects that are accessed

-The level of authentication required

-The accessibility time of the LDAP server

-The access level to an LDAP server

John Barrett is working as a network administrator at Blue Valley

Consulting. The organization has a number of branch offices all over

US. The employees of the organization access a centralized Linux

server located at the main branch. John has recently upgraded the

kernel of the centralized Linux server from kernel-2.4 to kernel-2.6.

John has also implemented RAID to avoid any data loss. After

implementing the RAID, John observes that the RAID acceleration is

low. As a result, the server performance is also degraded. To improve

the RAID acceleration, John needs to stabilize the speed of the RAID

device. For this, he decides to assign the value, 80000, to the

parameters specifying the speed of the RAID device. What should John

do to perform this task?

Execute the following commands at the shell prompt:

# echo 80000 > /proc/sys/dev/raid/speed_max

# echo 80000 > /proc/sys/dev/raid/speed_min


# echo 80000 > /sys/dev/raid/speed_limit_max

Red-Eye Experts is a leading developer of educational courseware. The

organization is located in California, and has about 200 employees.

The organization is divided into three departments: Production, HR,

and Marketing. In the existing setup, an NIS server is used to

authenticate the employees. However, the organization has decided to

recruit another 300 persons in the next two months. Due to the

expansion plans, Tom Wilkins, the system administrator, has decided

to configure an OpenLDAP server in the organization with the domain

“redeye.com”, to better manage the information about the employees.

For this, Tom needs to edit the “slapd.conf” file to specify the

domain components for the LDAP domain, and to specify the location of

the OpenLDAP database. Which directives of the slapd.conf file should

Tom use and how is Tom going to edit these directives to achieve his

objective?

To specify the domain components for the LDAP domain, Tom should

edit the Suffix directive, as shown:

suffix “ dc= redeye,dc=com”

To specify the location of the OpenLDAP database, Tom should edit

the directory directive, as shown:

directory /var/lib/redeye.com



suffix “ dc= redeye, dc=com”



directory /var/lib/ldap/redeye.com



suffix “ dc= redeye.com”



directory /lib/ldap/redeye.com



suffix “ dc= redeye.com”



directory /var/lib/ldap/redeye.com

Technology Systems is a leading developer of computer applications.

The organization has its head office in California and two branch

offices in New York and Toronto. There are three departments in the

organization: Marketing, Programming, and Accounting. The Programming

department is divided into two groups, Windows group and Linux group.

The branch offices are connected to the head office by a 56 Kbps

leased line. Now, each branch office runs as a separate entity, with

its own network, reporting structure, and constraints. The

organization has no centralized IT management group, and separate

administrators at each branch office manage the network. Since the

organization has multiple servers but no centralized management of

the information, it faces the data-related problems, such as data

redundancy and data inconsistency.

To avoid these data-related problems in the organization, Jim Lewis,

the system administrator at the head office, decides to install and

configure the OpenLDAP Directory service. Through the use of OpenLDAP

Directory service, Jim wants to provide authentication service in the

organization.

This authentication service authenticates the employees to the

directory server by providing the employees encrypted tickets for a

short duration. During the period when the ticket is valid, an

employee can access the directory service without providing a

password.

Now, to implement the above authentication mechanism, which

prerequisite software package must be installed and configured by Jim

before installing OpenLDAP, and what is the command entered by Jim to

install the prerequisite software package?

Jim must install the SASL software package

Jim must enter the following commands to install SASL:

# rpm –ivh cyrus-sasl-md5-2.1.15-3.i386.rpm

# rpm –ivh cyrus-sasl-plain-2.1.15-3.i386.rpm

# rpm –ivh cyrus-sasl-2.1.15-3.i386.rpm

# rpm –ivh cyrus-sasl-gssapi-2.1.15-3.i386.rpm

# rpm –ivh cyrus-sasl-devel-2.1.15-3.i386.rpm


Jim must enter the following command to install Kerberos:

# rpm –qa | grep krb5-server

Jim must install the OpenSSL software package.

Jim must enter the following commands to install OpenSSL:





Jim must enter the following commands to install Kerberos:





# rpm –ivh krb5-workstation-1.2.7-19.i386.rpm

6. Red-Eye Experts is a leading developer of computer applications, with its head office in Hew York. The organization has three departments: HR, Research, and Development. A directory service is configured in the HR department and all the employees in the rest of the departments access the directory service. The organization has two branch offices in London and Paris. These branch offices are connected to the head office in Hew York through Virtual Private Network (VPN). The directory service, in the HR department of the head office, is also accessed by the employees in the branch offices. So, there is a potential risk that a network failure between the head office and the branch offices can seriously affect the employees in the branch offices. To prevent this situation, John Barrett, the system administrator at the head office, decides to create multiple replicas of the directory service and configure these replicas in the branch offices. How, to maintain data consistency, John wants to synchronize the data which is stored in the main directory service and the replica servers. John wants to implement amechanism in such a way that when a replica server receives a write operation request from a client, it performs the write operation. After that, the replica server sends the modified updated entry values to all the replica servers and the main server. On receiving the modified entry values, the main server and the replica servers update the stored entries accordingly. How, which Replication Policy and Write Operation performing strategy should be employed by John to implement the above mechanism?

a. Multimaster Replication Policy using referralsb. Single-Master Replication Policy using chainingc. Single-Master Replication Policy using referralsd. Multimaster Replication Policy

9. Countryside Markets is a software application development company in U.S. The company maintains all the details of the software developed by the company in an OpenLDAP server. The company finds that some unauthorized people are accessing the OpenLDAP server to get information about the software contained therein. The company assigns the task to the system administrator, Chris Donaldson, to protect the OpenLDAP server from this threat. Chris finds that the company allows access to the OpenLDAP

server to the clients byasking for the DM to be accessed and for the password as plain text. To provide security to the OpenLDAP server, Chris decides to change the accessing method. Chris defines that whenever a client has to connect to the OpenLDAP server, the client sends a connection request to the OpenLDAP server. When the OpenLDAP server receives the request, it creates and sends a challenge to the client, which consists of an encrypted message from the server to the client. If the client has the encrypted key, it sends the key as the response to the challenge sent by the OpenLDAP server. If the key is verified, the OpenLDAP server allows the client to connect and access information from the OpenLDAP server.

Blue Moon Computers is a software development organization, which has development centers all over the US. Pat Greene, the system administrator at Blue Moon Computers, installs a LDAP server to store the information about the employees and projects running at different development centers. The Internet has facilitated the growth of Blue Moon Computers. Therefore, Pat decides to increase the accessibility of the LDAP server to all development centers through the Internet.

According to the company’s policies, the electronic mail address for a given employee is considered public information and the employee's home address is considered sensitive information. It must be protected to address employee privacy concerns. Easy accessibility to the LDAP server allows malicious users to try and access the LDAP server to obtain the home address and other such private and confidential information about various employees. Therefore, the server needs to be protected against such malicious users. Pat needs to implement Access Control List (ACL) to grant access privileges to the authenticated users.

Which of the following options contains the access control requirements to accomplish this task? 1,-The subjects accessing the LDAP server

-The objects that are accessed

-The level of authentication required

-The accessibility time of the LDAP server

-The access level to an LDAP server2,-Physical security

Blue Moon Computers is a leading developer of computer applications. The organization has three departments: HR, Research, and Development. The directory service is configured in the HR department only, and all the employees in the rest of the departments access the directory. Now, if the directory service fails due to a system failure, employees in all the three departments will be affected. To avoid this, Chris Donaldson, the system administrator, wants to make the directory service available in all the three departments. For this, Chris decides to create multiple copies of the directory service and install a copy of the Directory service in each department. Chris employs the Single-Master Replication Policy to synchronize the data stored in the main directory server and the Replica servers, to maintain data consistency.

Now, to perform the write operations to add, modify, or update the data, in the Directory service, Chris wants to implement a mechanism so that when an employee sends a write operation request to a replica server, the replica server sends the IP address of the main directory server to the employee. The replica server also sends a message to the employee along with the IP address. This message requests the employee to send the write operation request to the main directory server.

Which strategy, in the Single-Master Replication policy, is employed by Chris to perform the write operation? 1,Using referrals 2,Using chaining 3,Assigning unique sequence numbers to each update operation performed 4,Using referrals and Using chaining
