2015 is turning out to be the most spectacular year of high profile compromises across almost every vertical and many companies are starting to consider new options to raise the bar for intrusion detection and incident response, including deploying honeypots.
In this workshop we will present an overview of the current state of the art of leveraging open source tools to build a novel intrusion detection system inside the enterprise. We will discuss the pros/cons and ins/outs of several major open source honeypots as well as how to manage and deploy these sensors using the Modern Honey Network, Splunk, as well as integration into other systems such as ArcSight. We will discuss real world deployments of honeypots, what worked and what didn't as well as recommendations for getting the most out of these non-convention network sensors.

In Linux, a process is an instance of a running computer program. It's the basic unit of execution where a program is executed. Every process in Linux is assigned a unique Process ID (PID) which is used to identify the process.
Processes in Linux can be either in the foreground or background. Foreground processes are those that interact with the user, while background processes run without user intervention.
Linux processes inherit attributes and resource limits from their parent processes, and new processes can be created using the fork() system call. Child processes can further replace their memory space with a new program using the exec() system call.
Processes can be managed using various commands like ps (to display information about processes), top (to show currently running processes), kill (to terminate processes), and many others.
Linux provides a robust set of process management features, allowing for efficient multitasking and resource utilization. The Linux scheduler handles process scheduling, ensuring that CPU time is allocated effectively among running processes.
Overall, processes in Linux form the backbone of the operating system, enabling it to manage various tasks and run multiple programs concurrently.
CacheFS is a filesystem caching technology developed for UNIX-like operating systems .It is designed to cache the contents of a remote filesystem onto the local disk to improve performance by reducing the number of network requests needed to access frequently used files. CacheFS works by intercepting requests to access remote files and serving them from the local disk cache, rather than accessing them over the network every time they are needed.
CacheFS is used primarily in situations where network bandwidth is limited or where the latency of remote access is high, such as in WAN or satellite link scenarios. It is often used to speed up access to file servers, such as Network File System (NFS) servers.
some of its features have been incorporated into other caching technologies, such as the Squid web proxy cache.
NBD (Network Block Device) and nbdkit are related technologies in the realm of virtualization and storage. They allow you to work with remote block devices and create flexible storage solutions. Here's an overview of each:
1. NBD (Network Block Device):
NBD is a protocol that allows you to access remote block devices over a network, as if they were local block devices. It provides a way to export disk images or block devices from a server to clients, enabling remote access and manipulation of these devices.
Key features of NBD include:
Block-Level Access: NBD operates at the block level, allowing you to read from and write to specific blocks on a remote device.
Flexibility: It's used in various scenarios such as diskless booting, live migration of virtual machines, and remote disk access for storage solutions.
Network Transport: NBD operates over the network and typically uses TCP/IP as the underlying transport.
Read-Only and Read-Write Modes: You can access remote devices in both read-only and read-write modes.
2. nbdkit:
nbdkit is a pluggable NBD server, providing a flexible and extensible way to serve remote block devices. It acts as an NBD server that can be extended using various plugins, allowing you to create custom storage solutions tailored to your needs.
MariaDB and MySQL are both popular open-source relational database management systems (RDBMS) that are used to store, organize, and manage data. They are both based on the same core software, which was originally developed by MySQL AB, but MariaDB is a fork of MySQL that was created in 2009 due to concerns about the acquisition of MySQL by Oracle Corporation.
MariaDB and MySQL have many similarities, including their architecture, syntax, and functionality. Both databases use SQL (Structured Query Language) to manage data and support a wide range of programming languages. They also offer features such as replication, clustering, and partitioning to improve performance and scalability.
However, there are also some differences between MariaDB and MySQL. MariaDB has some additional features and improvements over MySQL, such as better performance, improved security, and more storage engines. MariaDB also supports more data types than MySQL and has more built-in functions.
Overall, both MariaDB and MySQL are powerful and reliable RDBMS options for managing data, and the choice between them may depend on specific needs and preferences.
Ceph: A Powerful, Scalable, and Flexible Storage SolutionYashar Esmaildokht
## Ceph: A Powerful, Scalable, and Flexible Storage Solution
Ceph is an open-source, distributed storage platform that offers a range of features, including object storage, block storage, and file systems. It provides a highly scalable, reliable, and flexible solution for managing your data.
Ceph's Key Components:
* RADOS (Reliable Autonomic Distributed Object Storage): Ceph's core storage component. It provides object storage capabilities and forms the basis for other services.
* RBD (RADOS Block Device): Ceph's block storage service. Allows you to create and manage block devices that can be attached to virtual machines or containers.
* CephFS (Ceph File System): Ceph's distributed file system. Offers scalable and reliable shared file system access for applications and users.
Ceph Backfill:
Backfill is a process used to repopulate data onto newly added OSDs (Object Storage Devices) in a Ceph cluster. Here's how it works:
1. Data Imbalance: When new OSDs are added, the cluster may have an imbalance in data distribution. Some OSDs might have more data than others.
2. Backfill Process: Ceph identifies the underutilized OSDs and starts copying data from overloaded OSDs to these new OSDs.
3. Data Balancing: The backfill process aims to achieve an even distribution of data across all OSDs in the cluster.
Ceph Scrub:
Scrubbing is a data integrity check that Ceph performs to detect and repair errors in stored data. Here's the process:
1. Data Verification: Ceph compares the data stored on different OSDs that hold replicas of the same object.
2. Error Detection: Any discrepancies between the data replicas are flagged as errors.
3. Data Repair: Ceph attempts to repair the errors by copying the correct data from another OSD.
Ceph Erasure Coding (EC):
Erasure coding is a technique used to increase data resilience and reduce storage overhead in a Ceph cluster.
* Data Chunking: Data is divided into smaller chunks, and a parity chunk is generated.
* Data Distribution: These chunks and parity chunks are distributed across multiple OSDs in the cluster.
* Data Recovery: Even if some OSDs fail, the lost data can be recovered from the remaining chunks and parity chunks.
Benefits of EC:
* Increased Data Resilience: Can tolerate more OSD failures without losing data.
* Reduced Storage Overhead: Reduces the total storage capacity required for storing data replicas.
* Improved Performance: Can enhance performance by spreading the data load across more OSDs.
Understanding Ceph, backfill, scrub, and EC is crucial for efficient operation and maintenance of a Ceph cluster. These mechanisms ensure data integrity, availability, and scalability, making Ceph a robust and powerful solution for storage management.
Software-Defined Networking (SDN) is a novel approach to network management that separates the control plane and data plane in network devices, allowing for centralized planning and control of networks. In traditional networks, routing decisions and network settings are made on individual switches and routers. In SDN, however, these decisions are made through a centralized software controller.
One key aspect of SDN is its high programmability. This means that network administrators can dynamically adjust network settings and controls using programming interfaces (APIs). This programmability enhances network flexibility and adaptability to changing needs.
SDN enables increased network efficiency, cost savings, and improved reliability and security through centralized management and software-based planning. This new approach to network architecture provides organizations with solutions and opportunities to enhance network performance and management. It is considered a leading-edge solution in information technology, offering greater capabilities for network improvement and management.
Service registry and service discovery are two important concepts in the field of distributed systems and microservices architecture.
Service registry is a centralized database that contains information about available services in a distributed system. Each service instance registers itself with the service registry upon startup, providing metadata such as its network location, endpoint, and health status. This allows other services to discover and communicate with each other without hardcoding IP addresses or endpoints.
Service discovery is the process of dynamically locating and connecting to services in a distributed system. Instead of relying on static configurations or hardcoded endpoints, services use a service discovery mechanism to query the service registry and retrieve the necessary information to establish connections with other services. This allows for more flexible and resilient communication between services, as instances can be added or removed from the system without affecting the overall functionality.
Service registry and service discovery are essential components of modern microservices architectures, enabling services to be loosely coupled, scalable, and easily deployable. Popular tools for implementing service registry and service discovery include Consul, etcd, Zookeeper, and Kubernetes.
