SSCP Practice Test Questions

If you’ve been studying for the SSCP exam, you may be looking for a good source of SSCP practice test questions. You’ll find that the SSCP Systems Security Certified Practitioner All-in-One Exam Guide covers the content in the exam but I’m hearing that test questions from the studISCope test banks are the most helpful.

(ISC)2 changes the questions in their live test bank regularly and they also update their practice test questions in the studISCope banks. Here’s a link: https://www.expresscertifications.com/ISC2/Catalog.aspx.

The SSCP is a good next step for many people that have taken and passed the Security+ exam. It will give you a good idea of what to expect from the premier security certification – CISSP – if you choose to take it. Also, many people have the experience to meet the requirements for SSCP, but not CISSP. As a reminder, the requirements are:

  • For the SSCP, you need one year of experience in one the seven (ISC)2 domains.
  • For the CISSP, you need five years of experience on one of the ten domains.

Good luck.

Protocol IDs for Security+ and SSCP Exams

Protocol IDs

If you’re preparing for the Security+ or SSCP exams, you’ll need to know a few of the protocol IDs used by TCP/IP. The protocol ID is a number embedded in the header of the packet to identify the protocol. It is used for many protocols that are not identified with a port number.

I recently wrote a blog titled Ports for Network+, Security+, and SSCP Exams which covered the relevant port numbers for these exams. Both port numbers and protocol IDs are used to identify protocols by devices such as routers and firewalls. However, they are different numbers. For example, Hypertext Transfer Protocol (HTTP) uses port number 80, but it is not accurate to say that it uses protocol ID 80. In fact, there isn’t a protocol ID that identifies HTTP.

Practice Test Question

Test your knowledge of protocol IDs with this question. This is an example that you may see on the SSCP exam.

Q. You want to block DoS attacks using ping at a firewall. What would you do?

A. Block port 1 at the firewall

B. Block protocol ID 1 at the firewall

C. Block port 6 at the firewall

D. Block protocol ID 6 at the firewall

Answer at end of blog

Protocol IDs

The following table identifies some of the commonly used protocol IDs that you may be tested on.

ProtocolProtocol ID
ICMP – Internet Control Message Protocol1
IGMP – Internet Group Management Protocol2
TCP – Transmission Control Protocol6
UDP – User Datagram Protocol17
IPsec ESP – Internet Protocol security Encapsulating Security Payload50
IPsec AH – Internet Protocol security Authentication Header51

You are more likely to be tested on the protocol IDs in the SSCP exam. If you do see this content on the Security+ exam, it will probably only focus on IPsec ESP or IPsec AH. If you want to see a full listing of protocol ID numbers, check out this list on Internet Assigned Numbers Authority (IANA).

Pass the Security+ exam the first time you take it:
CompTIA Security+: Get Certified Get Ahead: SY0-401 Study Guide

Routers and firewalls use access control lists (ACLs) to filter traffic. They can filter traffic based on IP addresses, network IDs, ports, and protocol IDs. The ports are used to filter traffic using well-known ports mapped to specific protocols. For example, you can block or allow outgoing email by closing or opening port 25, the well-known port for Simple Mail Transport Protocol (SMTP). Similarly, you can block ICMP traffic (used by ping) by blocking any traffic using protocol ID 1.

Q. You want to block DoS attacks using ping at a firewall. What would you do?

A. Block port 1 at the firewall

B. Block protocol ID 1 at the firewall

C. Block port 6 at the firewall

D. Block protocol ID 6 at the firewall

Answer: B

Ping uses Internet Control Message Protocol (ICMP) and ICMP is identified with protocol ID 1. Blocking protocol ID 1 blocks all pings including a denial-of-service (DoS) attack using ping.

Ports 1 and 6 are unrelated to ping or ICMP so would not have any effect on blocking pings.

Protocol ID 6 identifies Transmission Control Protocol (TCP) so by blocking protocol ID 6, you would block all TCP traffic.

Ports for Network+, Security+, and SSCP Exams

Ports for Network+, Security+, and SSCP Exams

If you’re planning on taking a certification exam such as CompTIA Security+, CompTIA Network+, or SSCP you should have many of the well-known ports memorized. The objectives for the CompTIA Network+ exam lists many of the protocols and the ports spelling out exactly what you need to know. Similarly, the objectives for the CompTIA Security+ exam lists several protocols with a statement to identify the ports for each. The SSCP exam objectives are very generic but do indicate port numbers are needed.

Well known port numbers are matched to specific protocols and when you see the port, you should be able to identify the protocol. Sometimes you may be given the protocol and be required to identify the port. There are 1024 well known TCP and UDP (numbered 0 through 1023) but you don’t need to memorize them all. However, you do need to know certain ports for the CompTIA Security+, CompTIA Network+, and SSCP exams.

Logical Ports

The well-known ports are logical ports and have nothing to do with physical ports. For example, port 80 is the port used for Hypertext Transfer Protocol (HTTP) and port 443 is the port used for Hypertext Transfer Protocol Secure (HTTPS).

In contrast, a physical port on a switch or router is used to make a physical connection between devices. You can touch the physical port while the logical port is simply a number embedded in the packet.

Every packet has both a source port and a destination port along with a source IP address and a destination IP address. The IP address is used to get the packet to the destination system and when the packet is received, TCP/IP uses the port information to determine how to handle the packet. This blog on Understanding Ports for Security+ describes the process of how logical ports are used in more detail.

Pass the Security+ exam the first time you take it:
CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide

TCP vs UDP Ports

Each of these logical ports are technically identified as either a Transmission Control Protocol (TCP) port or a User Datagram Protocol (UDP) port depending on which transport protocol they use. For example, HTTP can use either UDP port 80 or TCP port 80. It almost always uses TCP for guaranteed delivery but both TCP port 80 and UDP port 80 are reserved for HTTP.

Some protocols use only the UDP port. For example, Trivial File Transport Protocol (TFTP) uses UDP port 69 but not TCP port 69.

As you advance in the IT field, you’ll find that you need to know whether a protocol is using a TCP port or a UDP port. However for these exams, this depth of knowledge is rarely needed. Instead, you should focus on memorizing the port number. If you want to know specifically which transport protocol is used for any protocol, check out Wikipedia’s list of TCP and UDP port numbers.

Interestingly, Internet Assigned Numbers Authority (IANA) previously identified which transport protocol was used for each port in their Service Name and Transport Protocol Port Number Registry . However, they seem to have defaulted to just listing both TCP and UDP for each port. For example, Telnet (defined in RFC 854) only uses TCP port 23, not UDP. However, IANAs port number registry lists both TCP and UDP for Telnet.

SSCP Ports

The list of SSCP ports is a little easier for me to create. It’s simply all of the ports listed in the previous two tables. The (ISC)2 objectives do not list specific ports that you need to know but instead include the words “Commonly Used Ports and Protocols”. Theoretically, they can ask you about any of the ports but you’re unlikely to see anything other than what is listed here. If you do, please let me know.

Practice Test Question Answer

Q. What port do you need to close to block outgoing email?

A. Port 22

B. Port 25

C. Port 110

D. Port 443

Answer: B

Port 25 is used for SMTP and SMTP is used for outgoing email.

Port 22 is used for SSH, SFTP, and SCP but not for email.

Port 110 is used for POP3 but POP3 is only used for incoming email, not outgoing email.

Port 443 is used for HTTPS, not email.

Intrusion Detection Systems and Intrusion Prevention Systems

Intrusion Detection Systems and Intrusion Prevention Systems

If you’re studying for one of the security certifications like CISSP, SSCP, or Security+ you’ll come across intrusion detection systems and intrusion prevention systems. An intrusion detection system can detect and alert on potential intrusions, and an intrusion prevention system goes a step further and can block an attack. There’s a lot of depth to these topics and if you want to take a deep dive into the topics, check out NIST SP 800-94, Guide to Intrusion Detection and Prevention Systems (IDPS). This blog outlines the basics.

Host-based and Network-based

Intrusion detection systems (IDSs) and intrusion prevention systems (IPSs) are either host-based (HIDS or HIPS) or network-based (NIDS or NIPS).

  • Host-based. A host-based system is installed on a single computer such as a workstation or server. Its goal is to protect local resources on the host and it can detect attacks or intrusions on this system, but it cannot detect attacks on other systems.
  • Network-based. A network-based system monitors network activity and will include multiple sensors installed on network devices such as routers and firewalls. These sensors report activity back to a central monitoring console. It can detect network-based attacks, but it cannot detect anomalies on individual systems.

Pass the Security+ exam the first time you take it.
CompTIA Security+: Get Certified Get Ahead: SY0-401 Study Guide


Detection Methods

IDSs and IPSs primarily detect intrusions using one of two methods, knowledge-based or behavior-based.

  • Knowledge-based. This uses a database of known attack patterns and is similar to the signature file used to detect different types of viruses. It is also called signature-based and definition-based. The key is that the intrusion is using a known method that can be recognized. It’s important to keep antivirus definitions up-to-date to detect emerging threats. Likewise, it’s important to keep a knowledge-based IDPS signature file up-to-date.
  • Anomaly-based. Anomaly-based detection starts by creating a baseline of normal behavior. This baseline can take days or even weeks to create and is often called a training period. After the baseline is created, it then monitors activity and can report when activity varies from the baseline. For example, if network bandwidth usage is typically at 50 percent utilization for a specific connection, but increases to 95 percent sustained utilization, it indicates a change from the norm or an anomaly and will raise an alert. If the environment is updated or changed, the baseline needs to be updated.

Another method is known as stateful protocol analysis (also called deep packet inspection). In this method, traffic is examined for suspicious activity based on the protocol. For example, a typical File Transfer Protocol (FTP) session follows a predictable pattern where a user authenticates and then begins issuing commands. However, if the session deviates from the pattern, perhaps with the user issuing commands without authenticating, it may indicate an attack.

False Alarms

Both knowledge-based and anomaly-based systems are susceptible to false alarms (also called false alerts and false positives). In other words, they may report an attack that isn’t actually an attack. The goal of security administrators is to reduce the number of false alarms to a minimum, while also ensuring that actual attacks are reported.

Thresholds are used to set the limit between normal behavior and abnormal behavior that may indicate a potential attack. As an example, consider a TCP SYN flood attack where an attacker sends a SYN packet but not the ACK packet to complete a connection. If this happened once in a ten minute period, it probably isn’t an attack. If it happened one thousand times within a minute, it very likely is an attack. An IDS would use some number between 1 and 1,000 to as the threshold and when that number is reached, it raises an alert.

There isn’t a perfect number for any threshold so administrators seek a balance. If it is set too high, attacks will not be detected. If it is set too low, the IDS won’t be trusted due to the high number of false alarms. Most administrators are willing to accept some false positives if it will ensure they are notified when actual attack occurs.

Responses

When an IDS or IPS detects a potential intrusion it can respond either passively or actively.

  • Passive. A passive response will log the event and possibly provide a notification. The notification can be an email, text message, or page sent to key personnel, or perhaps a pop-up dialog box on the system.
  • Active. An active response will include the passive capability but will also take action to block the attack. It may terminate a connection or modify the access control list (ACL) on a router or firewall to block the attack.

IDS vs IPS

Active intrusion detection systems are often called intrusion prevention systems but this isn’t always the case. The distinguishing difference is that an IPS is placed inline with the traffic. In other words, all traffic to a network passes through an IPS giving the IPS the ability to block malicious traffic. In contrast, an active IDS may be able to block an attack but if it is not placed inline with the traffic, it can only block it after the attack has started.

DoS, Smurf, and Fraggle Attacks

DoS, Smurf, and Fraggle Attacks

Denial of service (DoS) attacks such as smurf and fraggle attacks are important to understand when studying for any security certification including Security+, SSCP, or CISSP. Smurf and fraggle attacks are similar but they have subtle differences.

DoS Attack

A DoS attack comes from a single entity and is intended to make a computer’s resources or services unavailable to users. DoS attacks against a server prevent the server from responding to legitimate requests from users. A distributed DoS (DDoS) attack comes from multiple attackers at the same time.


Pass the Security+ exam the first time you take it.
CompTIA Security+: Get Certified Get Ahead: SY0-401 Study Guide


Smurf Attack

A smurf attack uses Internet Control Management Protocol (ICMP) to send a broadcast ping with a spoofed source address. It’s easier to understand this by looking at one step at a time.

  • Normal ping. A regular ping sends one or more ICMP echo requests to a system and the system responds with one or more ICMP echo replies. This provides verification the remote system is operational. A regular ping uses unicast. In other words, the ICMP packet is addressed to one system from one system.
  • Broadcast ping. A broadcast ping is not normal. It sends the ICMP echo request to a broadcast address sending it to virtually all systems on the network. Each system will then respond to the system that sent it flooding this system with ICMP echo replies.
  • Spoofed source broadcast ping. The smurf attack spoofs the source address with the address of the victim, and then sends it out as a broadcast ping. Each system on the network will then respond, and flood the victim with echo replies.

There’s an important point to remember though. Routers do not pass broadcast packets. This was actually a change in RFC 2644 released in 1999 in direct response to smurf attacks and the use of networks as smurf amplifiers. RFC 2644 is an update to RFC 1812 which stated that a router must default to forwarding directed broadcasts. Routers today comply with RFC 2644 so smurf attacks are limited to a broadcast domain. They will not go beyond a router.

With this in mind, it would be rare to see a smurf attack. However, that doesn’t mean it won’t be tested.

Note: Many firewalls block ICMP packets to prevent any type of attack using ICMP. If a ping succeeds, it verifies that the system is operational. However, if a ping fails it doesn’t prove that the system is not operational. ICMP may be blocked preventing the ping.

Fraggle Attack

Fraggle attacks are similar to smurf attacks but instead of using ICMP, they use UDP ports 7 and 19.

As described earlier, the ping command uses ICMP and it is used to check if a system is operational. Tools are available that use UDP instead of ICMP and instead of checking to see if a system is operational, they check to see if the system is listening on a specific port. This is commonly done with many different types of vulnerability scanners used by both attackers and security administrators.

Chargen (character generator) is an older protocol described in RFC 864 (dated May 1983). A system listens on either TCP or UDP port 19 (known as the chargen port) for chargen requests. When a connection is established to this port, the system would respond with a constant stream of characters to the original system. Typically the original system would use TCP or UDP port 7 (known as the echo port) but this isn’t required. When the original system begins receiving the characters, it knows the target system is operational, and closes the connection.

In a fraggle attack, a spoofed broadcast packet is sent to port 19. The spoofed address is the address of the victim. Since it is broadcast, it goes to every system on the network. If port 19 is open and the character generator service is running on these systems, they will send a stream of characters to the victim.

Realistically, systems today will not have port 7 open or the chargen service running on port 19. Additionally, routers do not pass broadcasts so any attacks are limited to a single network. Said another way, it is very unlikely you will ever see a fraggle attack today.

Basic Protection

In addition to ensuring that routers are configured in compliance with RFC 2644 and do not pass broadcasts, there are some other basic steps that protect you from these types of attacks:

  • Disable unnecessary services and protocols. If a service or protocol is not needed on a system, it should not be enabled. I cannot think of a system in use today that would need the chargen service so it should be disabled if it is even available on the system.
  • Close unneeded ports. If a port is not needed, it should be closed on both network-based and host-based firewalls. With the port closed, all traffic is blocked and attacks are stopped.
  • Use ingress filters on firewalls. Don’t allow traffic into a network that shouldn’t be there. A common ingress filter on a boundary firewall (between the Internet and an internal network), blocks all traffic coming from the Internet with a spoofed private IP address.

Summary

In summary, DoS attacks such as smurf and fraggle attacks attempt to prevent a system from responding to legitimate requests. A smurf attack sends a broadcast ping with a spoofed IP address (the IP address of the victim), and ping uses ICMP. A fraggle attack uses UDP ports 7 and 19 instead of ICMP, and sends broadcast UDP traffic with a spoofed IP address (the IP address of the victim).

Three Factors of Authentication and Multifactor Authentication

Factors of Authentication

If you’re studying for one of the security certifications like CISSP, SSCP, or Security+ it’s important to understand the different factors of authentication, and how they can be intertwined as multifactor authentication. These are commonly known as something you know (such as a password), something you have (such as a smart card), and something you are (using biometrics). A basic understanding of these topics can help you correctly answer many different questions on authentication on any of these certification exams.

A previous post covered identification, authentication, and authorization. As a reminder, identification occurs when a user (or any subject) claims an identity. Authentication occurs when the user provides proof of the identity, such as with a password. Authorization grants access to resources based on the user’s proven identity.


Pass the Security+ exam the first time you take it.
CompTIA Security+: Get Certified Get Ahead: SY0-401 Study Guide


Something You Know

The something you know factor includes passwords and personal identification numbers (PINs). This is considered the weakest form of authentication because users often use weak passwords, give them out, or write their passwords down.

A strong password is complex and includes at least eight characters. Complex means that the password uses a mixture of upper case, lower case, numbers, and special characters. Some documentation indicates using three of the four character types is enough, while other documentation states that a complex password has four character types. The key is that more character types results in a more complex password that is harder to crack. However, the bigger point is that many users create passwords with only a single character type.

Troy Hunt did a great analysis of passwords that were stolen from Sony’s web sites and published on the Internet. He found that half used only a single character type and only 1 percent used any non-alphanumeric characters. Some of the top passwords were very simple: seinfeld, password, winner, 123456, purple, sweeps, contest, princess, maggie, and abc123. More than 64 percent of the passwords were found in common password-cracking dictionaries. Additionally, when users had accounts on two separate Sony sites, over 92 percent of them used the same password.

Password policies are often used to ensure that users create strong passwords and change them often. Some common password policy settings are:

  • Maximum password age. Requires users to change their password.
  • Minimum length. Ensures passwords have a minimum number of characters.
  • History. Remembers specific number of past passwords (such as last 5, or last 24 passwords). Prevents users from reusing the same passwords.
  • Minimum password page. Prevents users from changing their password right away. Used with the password history to prevent users from changing their password multiple times to circumvent the password history.

Something You Have

Smart cards and token, or fobs are common examples within the something you have factor of authentication. A smart card is a credit card sized card that holds key information about the user. Smart cards have certificates embedded in them using TLS and provide very strong authentication. This blog covers the differences between smart cards, a common access card (CAC), and a personal identity verification (PIV) card.

A fob (sometimes called a token) has an LED display that shows a number that changes regularly, such as every 60 seconds. This number is synchronized with a server. When users log into a website, they enter the number shown on the display to verify they have the token. This factor is often combined with another factor to provide multifactor authentication.

Something You Are

The something you are factor uses biometrics to prove a user’s identity. Fingerprints are very commonly used for authentication, but there are many other examples. Biometrics are often divided into two categories: physical biometrics and behavioral biometrics.

  • Physical biometrics are based on physical traits of an individual. It includes fingerprints, thumbprints, handprints, palms retina scanners, and iris scanners.
  • Behavioral biometrics is based on behavioral traits of an individual. It includes voice recognition, signature geometry, and key strokes on a keyboard.

Biometrics systems are susceptible to false readings. These are commonly known as:

  • Type 1 error. False Reject Rate (FRR). This occurs when a biometric system incorrectly rejects an authorized user.
  • Type 2 error. False Accept Rate (FAR). This occurs when a biometric system incorrectly identifies an unauthorized user as an authorized user.

Most biometric systems allow you to adjust the sensitivity of the system. For example, you can adjust it to minimize false rejections (FRR errors) but this will result in an increase in the false acceptances (FAR errors). The overall accuracy of a biometric system is identified with the crossover error rate (CER), where the FAR and FRR are equal. A biometric system with a lower CER is more accurate than one with a higher CER.



Multifactor Authentication

Multifactor authentication combines two or three of the factors. Two common examples are:

  • A user has a smart card and also uses a personal identification number (PIN)
  • A user has a token and also enters a username and password

It’s important to realize that multiple authentication and multifactor authentication are not the same thing. For example, if a user enters a pin (in the something you know factor), and a password (also in the something you know factor), this is not multifactor authentication.
