Guide to high volume data sources for SIEMJoseph DeFever
The document discusses the need for security teams to have access to more data from a variety of sources to address evolving security challenges. As adversaries become more motivated by lucrative opportunities and employ more evasive and patient attack methods, security teams need more context from diverse data sources to identify unknown threats, investigate long dwell times, and combat evasion techniques. Both basic attacks exploiting misconfigurations and advanced attacks require security teams to maintain visibility across on-premises and cloud environments and access security-relevant data for detections, investigations, and responses. High-profile examples that illustrate the need for more data include cloud-based data breaches, sophisticated supply chain attacks, and evolving ICS/SCADA and IoT attacks.
This document summarizes two cases where an active data breach was successfully detected using LightCyber's active breach detection solution. In the first case, a state-sponsored actor had been stealing intellectual property from a manufacturing company for 18 months before being detected. LightCyber detected anomalous network activity that revealed malware performing lateral movement. In the second case, a rogue employee at a media company had been infecting devices and stealing data for three months. LightCyber detected the employee's custom malware variant, exfiltration of data, and command and control traffic. Both cases showed that detecting active breaches requires analyzing a broad range of network and endpoint context.
The document provides 10 steps to safeguard a business from growing cyber threats. It notes that 72% of attacks target user identities and applications rather than servers and networks.

DATA BREACH REPRESENTS POTENTIAL EXISTENTIAL RISKRobert Anderson
Data breaches pose an existential risk to organizations as cyber criminals carefully plan attacks to infiltrate networks and steal data. A recent ransomware attack encrypted over two terabytes of a victim's data after exploiting outdated systems, demonstrating the importance of preparing for attacks. While the victim initially paid ransoms without notifying authorities, which only increased demands, bringing in experts allowed identifying the attack and implementing preventative measures. All organizations must proactively address cybersecurity and incident response plans to mitigate risks and prevent catastrophic data loss from attacks.

In order to ensure a company's Internet security, SIEM (Security Information and Event Management) system is in place to simplify the various preventive technologies and flag alerts for security events. Inspectors (SOC) investigate warnings to determine if this is true or not. However, the number of warnings in general is wrong with the majority and is more than the ability of SCO to handle all awareness. Because of this, malicious possibility. Attacks and compromised hosts may be wrong. Machine learning is a possible approach to improving the wrong positive rate and improving the productivity of SOC analysts. In this article, we create a user-centric engineer learning framework for the Internet Safety Functional Center in the real organizational context. We discuss regular data sources in SOC, their work flow, and how to process this data and create an effective machine learning system. This article is aimed at two groups of readers. The first group is intelligent researchers who have no knowledge of data scientists or computer safety fields but who engineer should develop machine learning systems for machine safety. The second groups of visitors are Internet security practitioners that have deep knowledge and expertise in Cyber Security, but do Machine learning experiences do not exist and I'd like to create one by themselves.

Malware is an application that is harmful to your forensic information. Basically, malware analyses is the process of analysing the behaviours of malicious code and then create signatures to detect and defend against it.Malware, such as Trojan horse, Worms and Spyware severely threatens the forensic security. This research observed that although malware and its variants may vary a lot from content signatures, they share some behaviour features at a higher level which are more precise in revealing the real intent of malware. This paper investigates the various techniques of malware behaviour extraction and analysis. In addition, we discuss the implications of malware analysis tools for malware detection based on various techniques.
This document introduces the need for a new security model to address the full attack continuum - before, during, and after attacks. Traditional security methods relying on detection and blocking are no longer adequate against modern threats. The threat landscape has evolved to include sophisticated, well-funded attackers employing techniques like zero-days, advanced persistent threats, and industrialized hacking for profit. Additionally, new business models and the growth of the Internet of Everything have expanded networks and attack surfaces. A new security model is needed to provide comprehensive visibility and protection across changing IT infrastructures and against evolving threats.

Inside TorrentLocker (Cryptolocker) Malware C&C Server Davide Cioccia
CryptoLocker was a ransomware trojan which targeted computers running Microsoft Windows and was first observed by Dell SecureWorks in September 2013. CryptoLocker propagated via infected email attachments, and via an existing botnet; when activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message, which offers to decrypt the data if a payment (through either Bitcoin or a pre-paid cash voucher) is made by a stated deadline, and threatened to delete the private key if the deadline passes. If the deadline is not met, the malware offered to decrypt data via an online service provided by the malware's operators, for a significantly higher price in Bitcoin

The document discusses information systems for supply chain management and identifies uncertainties, risks, and cybersecurity as key issues. It proposes a new approach for identifying and predicting supply risk under uncertain conditions and a complex solution for securing data in supply chain information systems. Several strategies are discussed for managing risks from new technologies like cloud computing, IoT devices, and DevOps services that are increasingly used in supply chain systems.
The document discusses the concept of "secure pipes", which refers to internet service providers integrating security functions directly into their network infrastructure to filter traffic before it reaches customers. This represents a paradigm shift from the traditional approach where customers were responsible for security after receiving traffic. Secure pipes involve three stages: 1) Filtering to block known bad traffic using signatures, 2) Exposing unknown malicious content through advanced analytics, and 3) Predicting future attacks by analyzing digital breadcrumbs from reconnaissance activities. The key benefits are applying security at internet speeds, gaining visibility from millions of endpoints, and allowing security teams to focus on more sophisticated threats.
FLOODING ATTACKS DETECTION OF MOBILE AGENTS IN IP NETWORKScsandit
This document summarizes a research paper that proposes a new framework for detecting flooding attacks in mobile agent networks. The framework integrates divergence measures like Hellinger distance and Chi-square over a sketch data structure. The sketch data structure is used to derive probability distributions from traffic data in fixed memory. Divergence measures compare the current and prior probability distributions to detect deviations indicating attacks. The performance of detecting attacks while minimizing false alarms is evaluated using real network traces with injected flooding attacks. Experimental results show the proposed approach outperforms existing solutions.

Evasion Streamline Intruders Using Graph Based Attacker model Analysis and Co...Editor IJCATR
Network Intrusion detection and Countermeasure Election in virtual network systems (NICE) are used to establish a
defense-in-depth intrusion detection framework. For better attack detection, NICE incorporates attack graph analytical procedures into
the intrusion detection processes. We must note that the design of NICE does not intend to improve any of the existing intrusion
detection algorithms; indeed, NICE employs a reconfigurable virtual networking approach to detect and counter the attempts to
compromise VMs, thus preventing zombie VMs. NICE includes two main phases: deploy a lightweight mirroring-based network
intrusion detection agent (NICE-A) on each cloud server to capture and analyze cloud traffic. A NICE-A periodically scans the virtual
system vulnerabilities within a cloud server to establish Scenario Attack Graph (SAGs), and then based on the severity of identified
vulnerability toward the collaborative attack goals, NICE will decide whether or not to put a VM in network inspection state. Once a
VM enters inspection state, Deep Packet Inspection (DPI) is applied, and/or virtual network reconfigurations can be deployed to the
inspecting VM to make the potential attack behaviors prominent.

MIST Effective Masquerade Attack Detection in the CloudKumar Goud
Abstract: Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. We propose a different approach for securing data in the cloud using offensive decoy technology. We monitor data access in the cloud and detect abnormal data access patterns. When unauthorized access is suspected and then verified using challenge questions, we launch a disinformation attack by returning large amounts of decoy information to the attacker. This protects against the misuse of the user’s real data. Experiments conducted in a local file setting provide evidence that this approach may provide unprecedented levels of user data security in a Cloud environment.

modeling and predicting cyber hacking breaches Venkat Projects
Analyzing cyber incident data sets is an important method for deepening our understanding of the evolution of the threat situation. This is a relatively new research topic, and many studies remain to be done. In this paper, we report a statistical analysis of a breach incident data set corresponding to 12 years (2005–2017) of cyber hacking activities that include malware attacks. We show that, in contrast to the findings reported in the literature, both hacking breach incident inter-arrival times and breach sizes should be modeled by stochastic processes, rather than by distributions because they exhibit autocorrelations. Then, we propose particular stochastic process models to, respectively, fit the inter-arrival times and the breach sizes. We also show that these models can predict the inter-arrival times and the breach sizes. In order to get deeper insights into the evolution of hacking breach incidents, we conduct both qualitative and quantitative trend analyses on the data set. We draw a set of cybersecurity insights, including that the threat of cyber hacks is indeed getting worse in terms of their frequency, but not in terms of the magnitude of their damage.
The document discusses building a smarter, simpler network architecture using intelligent access and application monitoring. It argues that next generation networks need high scalability, availability, and self-healing capabilities to handle growing traffic and complexity. The author advocates for an approach where network access and security/monitoring tools work intelligently together as a cohesive system, with the access providing context about network traffic to help tools like firewalls and intrusion detection systems operate optimally. Automating functions like load balancing and "heartbeat" packets that check tool health are presented as ways to proactively monitor the network and optimize tool performance.

2. Threat oday’s synergistic corporate infrastructure along with federation of their information is building
an agile and cohesive environment. However it also introduces newer challenges to protect information
assets from ge;ing into adversary’s hands. According to an article in Forbes , the cyber crime costs are1
projected to hit $2 Trillion by 2019 with cyber a;ack projected losses of at least $9.7 Billion in 2020 .2
With recent a;acks on Equifax, Kaspersky, SonicWall, Deloi;e, and Whole Foods its just ma;er of time
when these projections will turn into a reality.
Identifying cyber threats is particularly challenging. First, hackers collaborate across geographical
locations, making it difficult to trace the a;acking source. Second, complexity and a;ack payloads are
evolving rapidly, making it slow to monitor and prevent many vulnerabilities and consequences in
synergistic cyber networks. Third, the advanced persistent threats (APT) are implanted across multiple
stages, making it troublesome to catch real time incidents out of normal network traffic. Last but not
least, it is extremely hard to manage the volume, velocity, and complexity of the data generated by the
myriad of security tools. It can easily take months’ effort of even the most experienced security experts
to comb through these massive amount of data and find the needle in the haystack.
In order to build an intelligent and proactive security program, security evangelist and thought leaders
must investing some time on following,
1. Build a;acker’s portfolio
2. Behavior Analysis
3. Deeper learning and feedback loop
Building Attacker’s Portfolio - Know your adversary!
Asset Discovery
In order to build resourceful and content-driven security team, security thought leaders should identify
the critical assets the team is protecting. If you are protecting The Wall against Night Walkers than you
will need a Sworn Brother of the Night’s Watch to protect it (a GOT reference :)). However if you only
have public data classification and an adversary may not have any monetary gain than you can avoid
heavy investment in information security organization by focusing on automating against hacktivists,
script-kiddies or pranksters.

3. Cyber Adversary Profiling
Once asset discovery is performed, charactering cyber adversary and build an relevant a;ack’s profile
is next in line. Over the past decade, information security evangelist has done a splendid job in building
a template and database of various cyber adversary. But it comes with a disclaimer it is not a one size
fits all. Based on the data assets and where it lies in the infrastructure you start building control access
around them.

Cyber Kill Chain
Lockheed Martin coined the term Cyber Kill Chain and is aggressively adopted in security3
community to describe stages of cyber a;acks. The intrusion-centric model focuses on seven different
steps
1. Reconnaissance, information gathering
2. Weaponization, use of known exploits or create new ones
3. Delivery, plant malicious payload on target machines

Challenges • 2
4. 4. Exploitation, execute the exploit
5. Installation, install malware
6. Command and Center, create C&C to operate a;acks remotely
7. Action on objectives, perform the steps to achieve actual goals
Below is an example of one such cyber kill chain
Challenges • 3
5. Behavioral Analysis
The common thread across various forms of threats is the deviation of an asset or user’s behavior.
Security evangelist needs to map behavioral pa;erns to cyber adversary characterization. This
deviation can indicate fraudulent or malicious activity , which is important in detecting such a;ackers.
Behavior of users, devices, system accounts, and privileged accounts should be monitored to reveal
anomalies.
Deeper Learning And Feedback Loop
Next in line is implementing systematic solutions using the most advanced statistical and deep learning
techniques to detect and prevent threats in real-time. Each a;ack tree is implemented to cover certain
stage along the cyber kill chain. Once such a;ack trees are discovered an automated alerting process
must be triggered and first layer of incident responders must be trigger for a review. Responders can
than triage various trigger sources and decide on appropriate actions, like blocking the corresponding
web traffic, removing the responsible extensions, or acting over the suspicious segment. After a few
iterations one can build a supervised security threat models to tune overall detection rate.
In practice, malicious application, licitly or illicitly, draw characteristic signatures through their
network traffic logs. Building an artificial neural network would trace down these traffic pa;erns then
generate alerts that are potentially tied to different phases of the threats.

6. To identify lateral movement across net-flow data, we build graph model using PageRank algorithm to
measure the in/egress fluctuations of the endpoints across the subnets. In theory, the PageRank score of
each node corresponds to the net-flow counts among other nodes. Therefor a drastic score change of a
node reflects the impact of its neighbors and suggests possible propagation of suspicious actions.
Network intrusion detection can be the vital mechanism where the a;acker’s trace should be definitely
identifiable. Finding malicious activity on Visa network depends on humans’ intervention to properly
code and configure them. We create profiles of users behavior based on different network activity
related features, such as egress, ingress, data volume sent or received etc. Rareness of usage of
different access pa;erns, such as, protocol or port are also brought into consideration to determine
deviation from normal user’s behavior. Profiles are also created based on roles of employees. Deviation
of a user’s activity is determined based on a user’s own profile deviation and from his peer group’s
profile deviation. We use historical knowledge base and histogram approach to determine anomalies
for this net-flow-UBA based model.
We also profile network behavior in different network entity level i.e. VMSN servers, shared scanners,
printers etc. Using time series model we learn the normal behavior of network traffic pa;ern over time
using historical data and determine the risk of network flow in sliding window fashion. Using different
combination of features, we determine reconnaissance, port scanning, privilege escalation, lateral
movement, data exfiltration from network activity.
One of the very common a;ack scenario these days is Distributed Denial of Service (DDoS). Excessive
Domain Name system (DNS) request is widely used to instigate DDoS a;ack. Applying natural
language processing and machine learning techniques, we are able to determine the legitimacy of the
requested domains and determine whether it is coming from a;ackers or not. The distribution of
number of requests in sliding time window fashion is investigated to identify a;ack scenario. We also
determine the probability of a requested domain whether it is generated randomly or by malware
using deep neural network learning based LSM method.
Ports and protocol access pa;erns are profiled from network flow data. Using advanced ML-
classification algorithms, i.e. KNN, SVM etc., for a new network flow, we determine the probability of it
to be unknown or malicious compared to legitimate network flows. We apply clustering techniques to
firewall data to determine outliers for further investigation and determine the accurate functionalities
of firewalls.
We investigate users escalation in privileges based on historically occurred access pa;erns of that user
and the pa;ern of that escalated critical group. We also use different decision tree based approaches to
determine the sequence of events that created the escalation.
Challenges • 5
7. Some models at VSA follow specific rules based on which threat of an a;ack is determined. Specific
scoring mechanisms depending on various factors are outlined. When the event activity score is
beyond a threshold value, alert is generated and validated by security specialists. With their feedback,
the model keeps tuning itself over time. This is where self-learning comes into picture.
Future Prospect
As the sophistication and technology of cyber-a;acks continue to evolve, we foresee the following
trends will become the priorities of the next generation cyber security solutions in the coming years.
We’ll implement more intelligent deep learning model to understand cyber intelligence report and take
its up-to-date scenarios into consideration. The model shall have self-learning and evolving capabilities
to catch the most critical information from the intelligence. Ideally it can automatically update its own
design and thinking logic to adapt to the real practice.
We’ll also extend our protection measures to address today’s rapidly growing a;ack surface. This
moves beyond the network endpoints, to involve applications, databases, cloud environments and the
Internet of Things (IoT), etc.
We’ll continue to provide high detection rates with low computational overhead.
