601QUESTION 118 Due to regulatory requirements, server in a global organization must use time synchronization. Which of the following represents the MOST secure method of time synchronization?
602A. The server should connect to external Stratum 0 NTP servers for synchronization B. The server should connect to internal Stratum 0 NTP servers for synchronization C. The server should connect to external Stratum 1 NTP servers for synchronization D. The server should connect to external Stratum 1 NTP servers for synchronization
603Correct Answer: B Section: (none) Explanation
604Explanation/Reference: Configure your own Internal NTP hierarchical service for your network. It is possible to purchase Stratum 1 or Stratum 0 NTP appliances to use internally for less than the cost of a typical server. It is also possible to set up a private NTP server at a very low cost. The feasibility of setting up a commercial off the shelf (COTS) NTP server is evidenced in a recent effort to configure a Raspberry Pi computer as a Stratum-1 server. If you do decide to configure you own, please consider the following best practices:
605Standardize to UTC time. Within an enterprise, standardize all systems to coordinated universal time (UTC). Standardizing to UTC simplifies log correlation within the organization and with external parties no matter what time zone the device being synchronized is located in.
606Securing the network time service. Restrict the commands that can be used on the stratum servers. Do not allow public queries of the stratum servers. Only allow known networks/hosts to communicate with their respective stratum servers.
607Consider the business need for cryptography. Many administrators try to secure their networks with encrypted communications and encrypted authentication. I would introduce a note of caution here because although there are cryptographic services associated with NTP for securing NTP communications, the use of encryption introduces more sources for problems, such as requiring key management, and it also requires a higher computational overhead. Remember Segal's Law. Ideally, it would work to have three or more Stratum 0 or Stratum 1 servers and use those servers as primary masters. Remember Segal's Law: having two NTP servers makes it hard to know which one is accurate. Two Stratum 0 servers would provide a more accurate timestamp because they are using a time source that is considered definitive.
608QUESTION 119 When sending messages using symmetric encryption, which of the following must happen FIRST?

680Correct Answer: C Section: (none) Explanation
681Explanation/Reference: A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode.
682How To Protect your Server Against the POODLE SSLv3 Vulnerability
683On October 14th, 2014, a vulnerability in version 3 of the SSL encryption protocol was disclosed. This vulnerability, dubbed POODLE (Padding Oracle On Downgraded Legacy Encryption), allows an attacker to read information encrypted with this version of the protocol in plain text using a man-in-the-middle attack.
684Although SSLv3 is an older version of the protocol which is mainly obsolete, many pieces of software still fall back on SSLv3 if better encryption options are not available. More importantly, it is possible for an attacker to force SSLv3 connections if it is an available alternative for both participants attempting a connection.
685The POODLE vulnerability affects any services or clients that make it possible to communicate using SSLv3. Because this is a flaw with the protocol design, and not an implementation issue, every piece of software that uses SSLv3 is vulnerable.
686To find out more information about the vulnerability, consult the CVE information found at CVE-2014-3566.
687What is the POODLE Vulnerability? The POODLE vulnerability is a weakness in version 3 of the SSL protocol that allows an attacker in a man-inthe-middle context to decipher the plain text content of an SSLv3 encrypted message.
688Who is Affected by this Vulnerability? This vulnerability affects every piece of software that can be coerced into communicating with SSLv3. This means that any software that implements a fallback mechanism that includes SSLv3 support is vulnerable and can be exploited.
689Some common pieces of software that may be affected are web browsers, web servers, VPN servers, mail servers, etc.
690How Does It Work? In short, the POODLE vulnerability exists because the SSLv3 protocol does not adequately check the padding bytes that are sent with encrypted messages.
691Since these cannot be verified by the receiving party, an attacker can replace these and pass them on to the intended destination. When done in a specific way, the modified payload will potentially be accepted by the recipient without complaint.
692An average of once out of every 256 requests will accepted at the destination, allowing the attacker to decrypt a single byte. This can be repeated easily in order to progressively decrypt additional bytes. Any attacker able to repeatedly force a participant to resend data using this protocol can break the encryption in a very short amount of time.
693How Can I Protect Myself? Actions should be taken to ensure that you are not vulnerable in your roles as both a client and a server. Since encryption is usually negotiated between clients and servers, it is an issue that involves both parties.
694Servers and clients should should take steps to disable SSLv3 support completely. Many applications use better encryption by default, but implement SSLv3 support as a fallback option. This should be disabled, as a malicious user can force SSLv3 communication if both participants allow it as an acceptable method.
695QUESTION 136 Security administrators attempted corrective action after a phishing attack. Users are still experiencing trouble logging in, as well as an increase in account lockouts. Users' email contacts are complaining of an increase in spam and social networking requests. Due to the large number of affected accounts, remediation must be accomplished quickly. Which of the following actions should be taken FIRST? (Select TWO)
696A. Disable the compromised accounts B. Update WAF rules to block social networks C. Remove the compromised accounts with all AD groups D. Change the compromised accounts' passwords E. Disable the open relay on the email server F. Enable sender policy framework
697Correct Answer: EF Section: (none)
698Explanation
699Explanation/Reference: Sender Policy Framework (SPF) is a simple email-validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain comes from a host authorized by that domain's administrators.
700n a Small Business Server environment, you may have to prevent your Microsoft Exchange Server-based server from being used as an open relay SMTP server for unsolicited commercial e-mail messages, or spam. You may also have to clean up the Exchange server's SMTP queues to delete the unsolicited commercial email messages. If your Exchange server is being used as an open SMTP relay, you may experience one or more of the following symptoms: - The Exchange server cannot deliver outbound SMTP mail to a growing list of e-mail domains. - Internet browsing is slow from the server and from local area network (LAN) clients. - Free disk space on the Exchange server in the location of the Exchange information store databases or the Exchange information store transaction logs is reduced more rapidly than you expect. - The Microsoft Exchange information store databases spontaneously dismount. You may be able to manually mount the stores by using Exchange System Manager, but the stores may dismount on their own after they run for a short time.

726QUESTION 143 A security analyst is attempting to identify vulnerabilities in a customer's web application without impacting the system or its data. Which of the following BEST describes the vulnerability scanning concept performed?
727A. Aggressive scan B. Passive scan C. Non-credentialed scan D. Compliance scan
728Correct Answer: B Section: (none) Explanation
729Explanation/Reference: Passive scanning is a method of vulnerability detection that relies on information gleaned from network data that is captured from a target computer without direct interaction.
730Packet sniffing applications can be used for passive scanning to reveal information such as operating system, known protocols running on non-standard ports and active network applications with known bugs. Passive scanning may be conducted by a network administrator scanning for security vulnerabilities or by an intruder as a preliminary to an active attack.
731For an intruder, passive scanning's main advantage is that it does not leave a trail that could alert users or administrators to their activities. For an administrator, the main advantage is that it doesn't risk causing undesired behavior on the target computer, such as freezes. Because of these advantages, passive scanning need not be limited to a narrow time frame to minimize risk or disruption, which means that it is likely to return more information.
732Passive scanning does have limitations. It is not as complete in detail as active vulnerability scanning and cannot detect any applications that are not currently sending out traffic; nor can it distinguish false information put out for obfuscation.
