TaintDroid is a system that provides dynamic taint tracking and analysis for Android. It tracks privacy sensitive information like location, contacts etc. at variable, message, method and file levels with 14% overhead. Testing 30 apps found 20 shared information unexpectedly, like sending device IDs or location to ad servers. TaintDroid effectively demonstrates the need for stronger mobile privacy but has limitations like requiring OS modifications and false positives. Future work aims to reduce false positives, integrate crowdsourcing and detect privacy information leakage attempts.
SenSec: Mobile Application Security through Passive SensingJiang Zhu
The document proposes a smartphone-based behavioral authentication system called SenSec. It collects sensor data to build user behavior models. Features are extracted from the sensor data and used to build risk analysis trees to detect anomalies. When anomalies are detected, a certainty score is broadcast and can trigger authentication for sensitive applications. The system was tested on a dataset of 25 users, achieving over 98% accuracy in user identification. Extensions and integrations with other systems are discussed to enhance security, privacy, and energy efficiency.
Behaviometrics: Behavior Modeling from Heterogeneous Sensory Time-SeriesJiang Zhu
Over the decades, we have seen tremendous success in biometrics technologies being used in all types of applications based on the physical attributes of the individual such as face, fingerprints, voice and iris. Inspired by this, we introduce a new concept Mobile Behaviometrics, which uses algorithms and models to measure and quantify unique human behavioral patterns in place of human bio-attributes. Behaviometrics algorithms take multiple data from various sensors as input and fuse them to build behavioral models which are capable of producing application specific quantitative analysis on the unique individuals that were the originators of the data.
Traditional security models aim to provide confidentiality, integrity, and availability of information. They focus on authentication to ensure only authorized parties can access information and security policies to describe protected assets. Context-aware security models make security more flexible by adapting security levels and traceability based on contextual information like location, time, activity, and relationships. Context is captured as a security context and used to dynamically reconfigure security policies. Mirror worlds create virtual representations of the physical world that are updated in real-time based on sensor data feeds. They provide detailed models used for interaction and information access. Context-awareness enhances mirror worlds by incorporating contextual triggers to update security policies.

Vladimir Jirasek discusses securing mobile devices in the workplace. He covers consumerization challenges, mobile threats, and smart device security architectures. Mobile threats include malware, data loss, and integrity attacks. Good security architectures use access control, encryption, isolation, and permission-based controls. When allowing personal devices for work, companies should have clear policies, risk-based access rules, and forensic investigation agreements. Updating old devices and extending security monitoring to mobile are important parts of a correct mobile security approach.
IT Monitoring in the Era of Containers | Luca Deri Founder & Project Lead | ntopInfluxData
Network traffic monitoring tools are traditionally based on the packet paradigm where tools need to analyse each incoming and outgoing packet. As systems are moving towards a micro-service oriented architecture based on containers, the packet paradigm is no longer enough to provide IT visibility as services interact inside a system and not over a network where it is possible to install network sensors. This talk will explain how open source tools designed by ntop on top of InfluxDB allow packet monitoring tools to be complemented with container monitoring and thus implement a lightweight visibility solution for modern IT infrastructures.

The document discusses how networks and applications can become more aware of each other to improve the experience for end users. Currently, networks and applications operate independently without much visibility into each other. The document proposes that applications share information about end users and traffic with networks, and networks share information about topology, bandwidth, and resources with applications. This would allow applications to optimize content placement and resource usage, and networks to gain insights to better optimize traffic and provide new services. The document argues this type of programmable network can improve areas like security, performance, analytics and more.

Luiz eduardo. introduction to mobile snitchYury Chemerkin
Mobile devices broadcast information passively through protocols like mDNS and NetBios that can be used to profile and fingerprint individuals. This metadata includes a person's name, device details, social media profiles, locations visited and more. While concerning for privacy, there are some mitigation tips like disabling WiFi when not in use. In the future, passive profiling may become more advanced through integration with other tools and online databases to create detailed profiles of individuals based solely on information broadcast from their mobile devices.

Big Data and Internet of Things: A Roadmap For Smart Environments, Fog Comput...Jiang Zhu
1) The document proposes Fog Computing as a new platform that extends cloud computing to the edge of the network in order to address the needs of latency-sensitive IoT applications.
2) Two use cases are described to illustrate the key requirements of Fog Computing: a smart traffic light system that requires local subsystem latency of less than 10ms, and a wind farm that involves real-time analytics and coordination across a wide geographical area.
3) The key attributes that Fog Computing aims to address include mobility, geo-distribution, low and predictable latency, interplay between fog and cloud for data analytics, consistency in highly distributed systems, multi-tenancy, and multi-agency coordination.
Art and Science of Web Sites Performance: A Front-end ApproachJiang Zhu
People love fast web sites, but up until now developers have been focusing on the wrong area. Network (TCP, buffers, routing) performance and Backend (web server, database, etc.) performance are important for reducing hardware costs and improving efficiency, but for most pages 80% of the load time is spent on the frontend (HTML, CSS, JavaScript, images, iframes, and others). We will talk about the best practices for making web pages faster, provide case study from top web site, and introduce the tools we use for researching performance. In addition to know how to improve web performance, we will also try to gain an understanding of the fundamentals of how the Internet works including DNS, HTTP, and browsers. This talks was given as an Educational Series called Fog Computing Reading Group at Cisco Advanced Architecture and Research. The content is derived from the materials by Steven Sounders (Google/Stanford), Collin Jackson (Stanford/CMU) and Daniel Austin (eBay).
Improving Web Siste Performance Using Edge Services in Fog Computing Architec...Jiang Zhu
We consider web optimization within Fog Computing context. We apply existing methods for web optimization in a novel manner, such that these methods can be combined with unique knowledge that is only available at the edge (Fog) nodes. More dynamic adaptation to the user’s conditions (eg. network status and device’s computing load) can also be accomplished with network edge specific knowledge. As a result, a user’s webpage rendering performance is improved beyond that achieved by simply applying those methods at the webserver or CDNs.
Guest Lecture: SenSec - Mobile Security through BehavioMetrics Jiang Zhu
This document summarizes research on using mobile sensor data and behavioral biometrics for user authentication and activity recognition. It describes collecting data from accelerometers, GPS, WiFi and applications to build language models of user behavior. Scores are calculated to determine the likelihood a behavior belongs to a user or activity class. Authentication is triggered based on thresholds. The system was tested to identify users from single key presses and detect anomalies with days of training data at 80% accuracy. Future work involves expanded data collection, improved models, integration with security frameworks, and ensuring user privacy.
We introduce a new mobile system framework, SenSec, which uses passive sensory data to ensure the security of applications and data on mobile devices.
SenSec constantly collects sensory data from accelerometers, gyroscopes and magnetometers and constructs the gesture model of how a user uses the device.
SenSec calculates the sureness that the mobile device is being used by its owner.
Based on the sureness score, mobile devices can dynamically request the user to provide active authentication (such as a strong password), or disable certain features of the mobile devices to protect user's privacy and information security.
In this paper, we model such gesture patterns through a continuous n-gram language model using a set of features constructed from these sensors. We built mobile application prototype based on this model and use it to perform both user classification and user authentication experiments. User studies show that SenSec can achieve 75 accuracy in identifying the users and 71.3 accuracy in detecting the non-owners with only 13.1 false alarms.
The penetration of mobile devices equipped with various embedded sensors also make it possible to capture the physical and virtual context of the user and surrounding environment. Further, the modeling of human behaviors based on those data becomes very important due to the increasing popularity of context-aware computing and people-centric applications, which utilize users' behavior pattern to improve the existing services or enable new services. In many natural settings, however, their broader applications are hindered by three main challenges: rarity of labels, uncertainty of activity granularities, and the difficulty of multi-dimensional sensor fusion.
The document discusses using mobility traces and context information to detect loss or theft of mobile devices. It proposes converting traces and context into "behavior text" representations, then building an n-gram language model to establish a baseline for normal behavior. The model can detect anomalies indicating potential loss or theft events by flagging sequences with unexpectedly low probabilities. The approach aims to discover such events early for notification and recovery efforts.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

32. • Selected 30 applications with bias on popularity and access to
Internet, location, microphone, and camera
• 100 minutes, 22,594 packets, 1,130 TCP connections
• Of 105 flagged TCP connections, only 37 legitimate.
32
33. • 15 of the 30 applications shared physical location with an ad
server (admob.com, ad.qwapi.com, ads.mobclix.com,
data.flurry.com)
• Most traffic was plaintext (e.g., AdMob HTTP GET):
• In no case was sharing obvious to user or in EULA
• In some cases, periodic and occurred without app use
33
34. • 7 applications sent device (IMEI) and 2 apps sent phone
information (Phone #, IMSI*, ICC-ID) to a remote server without
informing the user.
One app‟s EULA indicated the IMEI was sent
Another app sent the hash of the IMEI
• Frequency was app-specific, e.g., one app sent phone
information every time the phone booted.
• Appeared to be sent to app developers ...
34
36. • Approach Limitations
• TaintDroid only tracks data flows (i.e. explicit flows).
• Malicious application can game out TaintDroid and exflitrate privacy sensitive
information through control flow.
• Taint Source Limitations
• IMSI contains country (MCC), network (MNC) and Station (MSIN) codes. All
tainted together, but heavily used in Android for configuration parameters.
Likely to cause false positives.
• Network only as sink . Sensitive information can propagate back from
network.
• Requires custom OS modification. No checks on native libraries
• Lack of evaluation data on power consumption
• User Interface: log is too technical and need further inspection
37
37. • TaintDroid provides efficient, system-wide, dynamic taint tracking and
analysis for Android
• 4 granularities of taint propagations
• Variable-level
• Message-level
• Method-level
• File-level
• 14% performance overhead on a CPU-bound microbenchmark.
• Identified 20 out of the 30 random selected applications to share
information in a way that was not expected.
• Findings demonstrated the effectiveness and value of enhancing Mobile
Privacy on smartphone platforms.
